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, ra…diation 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. .
some thing that is able to sustain oneself or itself independently
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 f…ishes 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 =(
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.
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 crossov…er. 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
All resources come from nature and all wastes are recycled.
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 substanc…es 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
love, care, and hope FOREVER!
through the interacting parts
i have no idea yeeno
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, thereb…y 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.
Nutrient Cycles, Predators and Prey, and Living Soil .
If the species continues to grow and reproduce offspring. If an ecosystem wasnt sustainable then is would become extinct over time.
