Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated fashion. Some of the more important components are: soil, atmosphere, radiation from the Sun, water, and living organisms. . Soils are much more complex than simple sediments. They contain a mixture of weathered rock fragments, highly altered soil mineral particles, organic matter, and living organisms. Soils provide nutrients, water, a home, and a structural growing medium for organisms. The vegetation found growing on top of a soil is closely linked to this component of an ecosystem through nutrient cycling. . The atmosphere provides organisms found within ecosystems with carbon dioxide for photosynthesis and oxygen for respiration. The processes of evaporation, transpiration, and precipitation cycle water between the atmosphere and the Earth's surface. . Solar radiation is used in ecosystems to heat the atmosphere and to evaporate and transpire water into the atmosphere. Sunlight is also necessary for photosynthesis. Photosynthesis provides the energy for plant growth and metabolism, and the organic food for other forms of life. . Most living tissue is composed of a very high percentage of water, up to and even exceeding 90%. The protoplasm of a very few cells can survive if their water content drops below 10%, and most are killed if it is less than 30-50%. Water is the medium by which mineral nutrients enter and are translocated in plants. It is also necessary for the maintenance of leaf turgidity and is required for photosynthetic chemical reactions. Plants and animals receive their water from the Earth's surface and soil. The original source of this water is precipitation from the atmosphere. . Ecosystems are composed of a variety of living organisms that can be classified as producers, consumers, or decomposers. Producers or autotrophs, are organisms that can manufacture the organic compounds they use as sources of energy and nutrients. Most producers are green plants that can manufacture their food through the process of photosynthesis. Consumers or heterotrophs get their energy and nutrients by feeding directly or indirectly on producers. We can distinguish two main types of consumers. Herbivores are consumers that eat plants for their energy and nutrients. Organisms that feed on herbivores are called carnivores. Carnivores can also consume other carnivores. Plants and animals supply organic matter to the soil system through shed tissues and death. Consumer organisms that feed on this organic matter, or detritus, are known as detritivores or decomposers. The organic matter that is consumed by the detritivores is eventually converted back into inorganic nutrients in the soil. These nutrients can then be used by plants for the production of organic compounds. .
Sustainability is a concern at the problems arising from the impact we have on the world has grown during recent decades. Basically, the word sustainability means how long you can keep doing what you are doing without coming to an end. Clearcutting forests without replanting is not sustainable--sooner or later you run out of forest. Using oil for fuel is not sustainable--eventually there will be no more oil. Farming practices which parch the soil and drain it of nutrients are not sustainable--they will turn the soil into desert. Sustainable practices include using solar and wind power which is not going to run out in billions of years, and which is not diminished by use, or crop rotations which keep the soil fertile, or replanting forests as they are used to ensure that there will be forests in the future.
Essentially, all green plants. These can also be referred to as autotrophs; self-feeding or self-sustaining. The trophic level is basically a food chain or furthermore a food web. The first level represents the primary producers which include photosynthetic organisms (alga and plants). The second level is primary consumers which include herbivores and ominivores. The third level represents secondary consumers carnivores and so on.
How does the water cycle the nitrogen cycle and the carbon cycle work to make an ecosystem sustainable?
Water Cycle - is the movement of water through Earth's ecosystems. Nitrogen Cycle - is the movement of nitrogen through ecosystems Carbon Cycle - is the flow of carbon as a solid, liquid, or gas through Earth's ecosystems Without all these three we will die and life won't be sustainable.
A self sustainable ecosystem is an ecosystem, that takes care of it self e.g. a fish tank would be an un-natural ecosystem since it is made. Not only is is made but also the fishes living their depend on we, the owners of the tank to feed them and clean their tank in order for them to survive. Thus such an ecosystem is comprised of interdependent organisms (plants,animals and insects) who would through a food chain create an energy flow.
primary producers ( autotrophs)......cycling?......constant source of energy??(sun). this is a Q on my AP bio summer work grrr and i dont get it rele either =(
Sustainable is ways of living and doing buisiness that use natural resources without using them all up. . So one of what we can do for the sustainable development is to use eco fashion products like eco fashion handbags. And here's a resource for that. http://www.envi.me/
A sustainable ecosystem is a system that survives, functions, andis renewed over time; a system in which people can continue to liveand flourish for many generations.
Prolong; lengthen or extend in duration or space; "We sustained the diplomatic negotiations as long as possible"; "prolong the treatment of the ..." In the music world it's known as the duration a tone is being held.
Sustainability is basically taking no more from nature than nature can replace. Man gets greedy and wants more. He cant have it.
Human systems and Ecosystems are dependent on the current atmosphere for necessary climatic conditions and molecules for life. Tampering with the atmosphere may cause far-reaching damage. Humans and ecosystems have evolved to depend on the current atmosphere. For this reason, new molecules that we put into the air can be poisonous to both us and ecosystems, can change the chemistry of the atmosphere, thereby damaging its functions, and may not have any way to break down harmful molecules.. Therefore, man-made gases can negatively affect our respiratory health, the health of ecosystems, and the overall climate of earth.. Sustainable living means maintaining the balance of molecules in the air by:. 1. Not changing any of the rates of biogeochemical cycles that determine atmospheric content, and. 2. Not putting any gases into the air that weren't there to begin with. This means a reduction in Carbon dioxide, sulfur oxides, nitrous oxides, and other types of damaging emissions.. 3. It also means that when we create new gases, we must create ways to dismantle these new gases into natural ones at their source..

Like so many lists of 10 there are a multitude of potential points espoused by one organization or another. All of these lists suggest "good" ideas and there is lot of crossover. One organization(ICMM) suggests: . Implement and maintain ethical business practices and sound systems of corporate governance. . Integrate sustainable development considerations within the corporate decision-making process. . Uphold fundamental human rights and respect cultures, customs and values in dealings with employees and others who are affected by our activities. . Implement risk management strategies based on valid data and sound science. . Seek continual improvement of our health and safety performance . Seek continual improvement of our environmental performance . Contribute to conservation of biodiversity and integrated approaches to land use planning . Facilitate and encourage responsible product design, use, re-use, recycling and disposal of our products . Contribute to the social, economic and institutional development of the communities in which we operate . Implement effective and transparent engagement, communication and independently verified reporting arrangements with our stakeholders The Hanover Principles (Expo 2000) suggest: . Insist on the right so humanity and nature to co-exist . Recognize interdependence . Respect relationships between spirit and matter . Accept reponsibilites for the consequences of design . Create safe of objects of long term value . Eliminate the concept of waste . Rely on natural energy flows . Understand the limitations of design . Seek constant improvement by the sharing of design
Newton's first law of motion states that an object not in motion will stay still unless acted upon by a force. Also, an object in motion will continue in motion at a constant velocity in a straight line unless acted upon by another force.
When the governing elite of a particular government wants to raise taxes, they claim that something that most people consider essential, such as fire protection, must be cut. They do not mention other things that could be cut because they want people to feel there is a crisis that require higher tax rates. In most cases, an analysis of the government's budget shows that it has been growing faster per capita than the rate of inflation.

Every body continues to move with a uniform speed or remains at rest until a force is applied to change its state. This law is also called the law of Inertia.
Sustainability refers to the ability of something to last and support itself without subsidy from another source. Such as a government implementing a pension plan. The plan would need to rely on contributions by the citizens to sustain itself. This would make the plan sustainable if it didn't need the government to top it up every now and then.

sustainbility is when a population can maitain itself consitstanly throughout a period of time where its population is steady not rising or decresing.
Have you ever heard of sustainable tree's?. Well in that context it means that if you pull down a tree you always replace it afterwards.. Hope this kinda helps 8)
The phrase "Black is Beautiful" first came from the 1960s writings of Steve Biko, of South Africa , who was part of the "Black Consciousness Movement". In his book, 'I Write What I Like', Mr. Biko explained the meaning behind his slogan as this: "man, you are okay as you are, begin to look upon yourself as a human being." The politics of the Black Panthers and the sermons of Malcolm X made the expression more widely known in the USA, and most people wrongly attribute the quote to Malcolm X. "Black is Beautiful" was a rallying cry, a movement against the idea that Blacks have less attractive or desirable characteristics and to discourage changing the natural African features. The slogan intended to discourage people from feeling they needed to change by: . bleaching/whitening their skin . straightening their hair . having plastic surgery to make a narrower nose The slogan was meant to create self pride and pride within the race, so people (especially girls and women) did not continue to feel they needed to alter their physical being just to fit in. They called this an internalized racism that Blacks carried inside and needed to end. See Related Link
This was first achieved in the Chicago pile, 1942. Enrico Fermi was the team leader.
The principles of sustainable development refers to the organizingprinciple for human life on a finite planet. It also refers to theposits of a desirable future state for all human societies to livein desirable conditions without undermining the sustainability ofthe natural system and the environment.
1) eliminate systematic increases in concentration of substances from the earth's crust in natural systems 2) eliminate systematic increases in concentrations of substances produced by society (i.e. compounds not found in nature) in natural systems 3) eliminate systematic physical degradation of nature through over-harvesting, introduction and other forms of modification (i.e. actions that prevent natural systems from performing the services upon which we depend) 4) eliminate the systematic undermining of people's capacity to meet their needs

First aid is aid which is given to anyone at any place withavailable things, before arrival of actual medical team. The basic principles of First aid are: . To preserve life . To prevent deterioration of the condition . Provide reassurance . Ask the actual help(medical team) and give the necessaryinformation to the doctor.
if we weren't we would run out of basic things we need for living like food, oxygen and fuel
How sustainable future of natural resources can be developed applying the various appropriate conservation principles?
it may be best done by applying and using more and more renuwable resources as solar, wind ,geothermal etc. the main principle may be- . - reuse and recycle the existing resources. . - apply best management methods. . - spread awareness . - innovation of new technology to boost resources and stop misuse.
Hi!!! Im guessing you are in Grade 7 because i have this question too. Well the answer is simple. i got it from Figure 2.17 on page 51 .... : Modern communities often destroy natural habitat when they expand. YOUR WelCOME !!! :) --Emmy Ionian ..... :) //Real name Mary Y . :)
In summer, growing plants remove magnesium ions from the soil to make chlorophyll. In autumn, these plants release magnesium when they die and decompose. In spring, new plants will grow in this same area.
The general principals of first aid is to remain calm, keep trackof the time, check for breathing and a heartbeat, and use CPR ifneeded. If there is an open wound, you may want to use anantibacterial ointment. Get medical attention if needed.
Rene Descartes' first principle of philosphy is "I think therefore I am" (or in the original French, je pense donc je suis).
I'll get you started. Using the definition of the derivative: For f(x) = xsinx this gives: Recall that From here you should be able to finish it out. Post back if you'restill having difficulties.
the general principles of first aid are: 1.take charge of the situation at once. 2.see how badly the victim is hurt.
Even the most productive only has 4 levels. If you start with 100%energy in the first level (plants) only 10% is passed on to thenext level. For the third level only 10% of 10% is passed on. So starting with 100%, the second level can have 10% to use, thethird level can have 10% of 10% or 1% to use. By the fourth levelehere is 10% of 1% left to substain any life. That is 0.1%. Onlythe most diverse system can have up to 4 levels. That is usuallyrain forests or jungles.
Arthur Tansley . Here is some further information . Tansley's early publications focused on palaeobotany , especially fern evolution .  Tansley founded the botanyjournal NewPhytologist in 1902 to serve as "a medium of easycommunication and discussion between British botanists on allmatters . . . including methods of teaching and research". It wasnamed after the Phytologist , a botanical magazine publishedbetween 1842 and 1863.  In establishing this journal,Tansley's aim was to provide a venue for the publication of "notesand suggestions"; existing botanical journals only publishedrecords of completed research.  He remained editor of thejournal until 1931.  . Tansley's introduction to ecology came in 1898 when he readWarming's Plantesamfund (in its German translation, Lehrbuch der Ã¶kologischenPflanzengeographie ). Reading the book provoked him to "[go] outinto the field to see how far one could match the plant communitiesWarming had described for Denmark in the English countryside". In1903 he learned of the work done by the Smith brothers in mappingthe vegetation of Scotland and Yorkshire. The work was initiated byRobert Smith and continued by his brother, William Gardner Smith (in conjunction with CharlesEdward Moss ) after Robert's death.  In 1904 Tansley suggested theformation of a central body for the systematic survey and mappingof the British Isles. This led to the establishment of the "CentralCommittee for the Survey and Study of British Vegetation" byTansley, Moss, William Smith and T. W.Woodhead ,  with the support of Marcel Hardy, F. J. Lewis, Lloyd Praeger and W.M. Rankin. These eight formed the original committee,  with Tansley as itsleader.  F. W. Oliverlater joined the group as its ninth member. The name of the groupwas later shortened to "The British Vegetation Committee". The aimof the group was to coordinate ongoing studies and standardise themethodology being used. The committee met twice more in 1905 andproduced a six-page pamphlet, Suggestions for Beginning SurveyWork on Vegetation .  . In 1911 Tansely, in conjunction with the British VegetationCommittee, organised the first InternationalPhytogeographic Excursion (IPE).  He was inspired by a plantgeography tour of Switzerland organised by Swiss botanist CarlSchrÃ¶ter in 1908, which introduced him not only tovegetation types, but also to botanists from other countries. Theconnections made between Tansley and American ecologists Henry Chandler Cowles and Frederic Clements helpedbuild a philosophical and methodological link between British andAmerican plant ecology.  Other attendees includedSchrÃ¶ter, Swedish botanist Carl Lindman , and Germanbotanists Oscar Drude and Paul Graebner . Tansley's book Types of BritishVegetation was prepared with an eye to serving as a guide tothe vegetation for the attendees of the first IPE.  The second IPE in 1913 washosted by Cowles. This brought Tansley to America.  . In 1913, the British Vegetation Committee organised the British EcologicalSociety (BES), the first-ever professional society ofecologists. Tansley served as its first president, and was firsteditor of the Journal ofEcology , a position he held for 21 years.  In 1915 he was elected a Fellow of the Royal Society , and in 1923he was elected president of the Botanical Section of the British Association for the Advancement ofScience . At the Imperial Botanical Congress in 1924 he wasappointed chairman of the British Empire Vegetation Committee. Heserved as president of the BES a second time in 1938.  . William S. Cooper considered Tansley's most influential publications synthesisedindividual studies into a whole.  In 1935 Tansley published "Theuse and abuse of vegetational terms and concepts"  in which he introduced the ecosystem concept. [fn 1]  In the 1930s ecologicalthinking was dominated by the work of Clements, who thought of ecological communities asorganisms, and associations as superorganisms .  Tansley devised the concept todraw attention to the importance of transfers of materials betweenorganisms and their environment,  regarding ecosystems as thebasic units of nature.  ". Though theorganisms may claim our prime interest, when we are trying to thinkfundamentally, we cannot separate them from their specialenvironments, with which they form one physical system.  . ". Tansley's interest in teaching led to the production of the Elements of Plant Ecology in 1922, which was followed by Practical Plant Ecology in 1923 and Aims and methods inthe study of vegetation in 1926, coauthored with Thomas Ford Chipp .  The last book, edited for theBritish Empire vegetation committee, was extremely influential notjust in defining ecological methods but in highlighting the needfor a complete inventory of the empire's "vegetational assets".With this information, it would be possible to efficiently managethe vast natural resources of the empire.  Tansley's most comprehensivework, The British Islands and Their Vegetation was publishedin 1939. In recognition of this achievement, he was awarded the Linnean Medal in1941.  . During the Second World War Tansley became committed to conservation , and thiscontinued through post-war reconstruction. He chaired a committeeof the BES that formulated a policy on nature reserves and led to theformation of the NatureConservancy ,  which he also chaired.  Tansley's conservation work wasthe basis cited for his knighthood in 1950.  . Tansley was introduced to psychology by a former student, BernardHart , who worked as a doctor in mental hospitals nearLondon. While working for the Ministry of Munitions during theFirst World War, he had a dream which was described as "one of themajor turning points in his life" - from this dream came Tansley'sinterest in Freud and psychoanalysis .  In 1920 he published The NewPsychology and its Relation to Life , one of the first booksthat attempted to introduce the ideas of Freud and Carl Jung to a general audience. The bookwas a bestseller, selling 10,000 copies in the United Kingdom and4,000 in the United States. In 1922 Tansley spent three months withFreud, and the following year he moved his family to Vienna for ayear. Although he later returned to botanical pursuits, Tansleyremained in contact with Freud and wrote his obituary.  Recent research by Peder Ankerhas suggested a close theoretical relationship between Tansley'secology and his psychology. 
The two processes that sustain ecosystems and the biosphere are one-way energy flow and nutrient cycling. These two processes are linked through the natural services that are components of the earth's natural capital.
The three principles of sustainability are Solar Energy, Chemical Cycling, and Biodiversity. Solar Energy: Involves the use of the sun to provide life to the plants, thereby providing life (and light and warmth) to this planet. Without the sun, or rather, solar energy produced by the sun, plants could not grow. Without plants, the consumers of said plants would not survive. This is why Solar Energy is important in regards to the principles of sustainability. Chemical Cycling: Involves the transfer of chemicals such as nutrients and minerals from the soil and solar energy transferring to plants, then transferring to the animal that eats the plant (herbivore), transfer of the same nutrients to the animal that eats the herbivore (carnivore), and the transfer of the nutrients from the carnivore to fungi, and then the nutrients and minerals are transferred back to the soil to be recycled. Chemical Cycling involves producers (such as plants), consumers (the herbivore and carnivore) and decomposers (the fungi/decomposition of the consumer to return to the soil). Biodiversity: The term is short for "Biological Diversity" and refers to the many variances of life on the planet, the natural habitats, and natural resources. Natural life would be animals, plants, and microorganisms. Natural habitat examples are forests, oceans, and deserts. Natural resource examples are air and water. Biodiversity, variances in species, contributes to evolution of said species, and humans rely on biodiversity to survive, just as all animals do as well, along with the planet.
Biodiversity contributes to the sustainability of an ecosystembecause different species in a given ecosystem depend on eachother.
The first principle of wound care is the removal of nonviable tissue, including necrotic (dead) tissue, slough, foreign debris, and residual material from dressings.
How can the human system be modified into a sustainable ecosystem in balance with other natural ecosystems without losing the benefits of modern civilization?
In brief, reduce the number of humans. Our modern civilisation, technology, medicine etc. has enabled our population to grow beyond what is sustainable if we are all to have the same level of benefits. we all need to accept a lower standard of living, mainly less energy spend per head, if we want a high population.
I think you tube has made use of technology in an efficient manner and has made it possible to sustain in the market for a longer run.
How does tourism and urbanization are destroying the mountain ecosystem and what are the measures are to be taken for sustainable mountain development?
Mountains are one of the world's most important tourist destinations. But tourism presents both opportunities and dangers for mountain ecosystems. It is a double edged sword. The clean, cool air and awe-inspiring scenery of mountain areas, combined with the unique customs, arts, crafts and culinary traditions of the communities that live there, make trips to the mountains attractive holiday options. Tourism revenues have become a primary source of income for many mountain communities. Yet, the influx of visitors into mountain regions poses a threat to these unique and often pristine environments. t can degrade and stress fragile mountain ecosystems, destroying the qualities that make these environments so alluring. Mountains are among the worlds most important repositories of biodiversity, yet construction, pollution and noise all threaten this precious asset. Litter and waste have emerged as key problems, as well as trees being felled to supply timber and fuel wood which again leads to further environmental impacts. The mysticism of sacred mountain sites is often diminished by the numbers of people who come from all over the world to make pilgrimages. Tourism means more transportation networks and links, which can blight the mountain environment, disrupt traditional ways of life. Building ski runs often involves destroying swathes of forest, planting pylons for chairlifts and cable cars and building roads and tunnels. In the Alps, emissions from the millions of vehicles that bring visitors to the slopes threaten the health of trees and worsen the effects of global warming. Paths and ski runs harm sensitive mountain ecosystems and disturb plant and animal life. The following are the measures which can be taken for sustainable development i) Mountains Ecotourism : Ecotourism can help reduce poverty and hunger, a key issue in mountain areas where a high proportion of the world's poor and food-insecure live. It also has considerable potential for strengthening communities and for protecting mountain ecosystems. Can help reduce poverty and hunger, a key issue in mountain areas where a high proportion of the world's poor and food-insecure live. It also has considerable potential for strengthening communities and for protecting mountain ecosystems. ii) Mountain tourism needs to be developed according to specific local conditions and cultures, an approach that will help communities gain a niche in an increasingly competitive market. iii) Policy-makers could favor activities that build on local knowledge and traditions to ensure that tourists respect the natural and cultural diversity of the places they visit and encourage mountain people to view their home as a source of pride. iv) the tourism industry needs to be developed as part of an overall economic development strategy, with diversification to ensure local economies do not become reliant solely on tourism revenue. v) Governments can help mountain communities by investing profits in programmes to ensure sustainable livelihoods for local people. Non-governmental organizations and the private sector can also help get the tourism equation right by offering education and training in responsible tourism practices.
Popular sovereignty is the idea that the people are the source of authority and power in government. "In free governments, the rulers are the servants and the people their superiors and sovereigns." - Benjamin Franklin
There was no first ecosystem on Earth. There were just different ecosystems in different parts of the world.
gravity Dude are you dumb? It's the "principle of inertia." Think thats wrong take it up with my physics teacher.
If the species continues to grow and reproduce offspring. If an ecosystem wasnt sustainable then is would become extinct over time.

All legislative powers herein granted shall be vested in a congressof the united states,which shall consist of a senate and house ofrepresentatives. "America's First Principles Foundation of American freedom and liberty Rejecting the oppression of the past, America's Founding Fathersestablished the American republic on our First Principles to secureour freedom and liberty. We are the first, perhaps the only nation that holds asself-evident truths that all men and women are created equal andare endowed by their Creator with certain unalienable rights; andthat governments are instituted to protect those rights and derivetheir just powers from the consent of the governed. Stateddifferently, America was founded on certain First Principles: * The rule of law is a First Principle that mandates that the lawgoverns everyone * The First Principle of unalienable rights recognizes thateveryone is naturally endowed by their Creator with certain rights * Equality is a First Principle that recognizes that all personsare created equal * The First Principle of the Social Compact recognizes thatgovernments are instituted by the people and derive their justpowers from the consent of the governed * The First Principle of limited government means that theprotection of unalienable rights is the legitimate purpose andlimit of government requires the government to be strong enough tofulfill its purpose yet limited to that purpose A final First Principle is the right to declare revolution when theother First Principles are being infringed by the government. Our Declaration of Independence explains that these foundationalideas were the philosophical underpinning of the AmericanRevolution. Once independence was secured, the Founding Fatherslabored to ensure that the Constitution became the livingembodiment of a government based on these First Principles." -Michael Warren ( the philosophy of popular sovereignty )
The first principle of Islam religion is monotheism. That is to worship Allah (God in English and same God worshiped by Jews and Christians) as the one and only one God with no partner, no son, no father, no companion, no associate, and no equivalence. Refer to questions below for more details.
There isn't anywhere that lists an exact date for the discovery of the Archimedes Principle. The closest that could be found was that the special event occurred some time 2200 years ago somewhere between 287 BC and 212 BC.
