Ecosystems

A pyramid can represent the energy transfer in an ecosystem in two ways:

First, right side up a pyramid can represent the number or volume of organisms at each level of the food chain. The energy transferred from each organism lower down on the food chain to the next higher up is not 100 percent efficient, so fewer organisms can exist at each higher level of the food chain.

Inverted, the pyramid is a simple model of how much total energy it takes to produce a single organism at a level in the food chain. organisms at the bottom taking the least, and those at the top taking the most total energy.

Secondary succesion is the succession that occurs after the initial succession has been disrupted, and some plants and animals still exist. It is usually faster than primary succession.

Tigers do not live in the wild in California. They are native to parts of Asia, mainly India, where they inhabit various forest habitats. In California, tigers are often found in accredited zoos and wildlife sanctuaries.

Factors that affect colloids include particle size, particle charge, temperature, and presence of electrolytes. These factors influence the stability and behavior of colloidal systems.

Organisms in the lowest trophic level of an ecosystem are typically primary producers, such as plants and algae. These organisms convert sunlight into energy through photosynthesis, forming the basis of the food chain and providing energy for all other organisms in the ecosystem.

Seed plants have the advantage of producing seeds, which are protected structures that contain the embryo and nutrients to support growth. Seeds are better suited for dispersal and survival in various environments compared to spores, which are typically single-celled and more vulnerable to desiccation and other external factors. Additionally, seeds provide a means of dormancy, allowing plants to endure unfavorable conditions until conditions are favorable for germination.

The types and numbers of animals in an ecosystem are determined by factors such as climate, habitat availability, food resources, competition with other species, and predation. These factors influence the distribution and abundance of different species within an ecosystem.

The ecosystem that would experience the most drastic changes in a 24-hour period would be an intertidal zone. This is because an intertidal zone is exposed to all the changes in the tide during all times of the day. The intertidal zone is the portion of the shoreline that is covered with water at high tides and exposed to the air during low tides.

Living things that live in soil include earthworms, ants, beetles, bacteria, fungi, and various types of microorganisms. These organisms play important roles in the soil ecosystem by breaking down organic matter, cycling nutrients, and aerating the soil.

About 90% of the energy is lost as it is transferred between trophic levels. This is due to factors such as cellular respiration, heat loss, and incomplete digestion and assimilation of food. The energy that remains is used by organisms for growth, reproduction, and other metabolic processes.

Yes, an ecosystem includes all the biotic (living) and abiotic (non-living) elements in a given area that interact with each other. Biotic elements include plants, animals, and microorganisms, while abiotic elements include soil, water, sunlight, and temperature.

For water to be drinkable (potable) it has to be free of microorganisms and of chemical contamination. The standards for agricultural water are much more relaxed. It doesn't mean that you will get sick from it, but it is a big risk.

• Sexual reproduction mixes the genetic inheritance for each generation;
• Different environmental pressures on different species - only those species that have the best characteristics to survive the environmental pressures will survive long enough to reproduce and leave their genes for the next generation.

well just think this, if there were no animals, the plants wouldn't survive. and vis versa

This is true for a few reasons:

1) Plants give off oxygen as a byproduct of the process of photosynthesis, we require oxygen.

2) In the same sense, plants use carbon dioxide in carbon fixation (to make glucose) And humans (as well as other heterotrophs) give off CO2 as a waste product of cellular respiration

3) Plants capture the energy of the sun... (we don't) so where would our energy come from if we didn't have something to capture what we can't?

Hope that is enough to go on....

The process by which nitrogen gas is converted into a usable form for life is called nitrogen fixation. This process is carried out by certain types of bacteria and archaea, which convert nitrogen gas into ammonia or other nitrogen-containing compounds that can be used by plants and other organisms.

Energy is a variable that always decreases as it flows through trophic levels due to the second law of thermodynamics, which states that energy is lost as heat during each transfer.

The biomass pyramid best traces the flow of matter through an ecosystem, as it illustrates the total amount of living organic matter within each trophic level. This helps to show the energy transfer and efficiency of the ecosystem, with each level being supported by the level below through consumption and assimilation of energy.

A community of organisms is made up of populations of differnet species that interact with each other in some way.

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.

If you are in the woods and you find an oddly shaped tree that is the shape of a table it is living, but if you bought it in a store it has been dead for a while. So in the wilderness it's like you and me, in your living room it's like a dead person.

Photosynthesis converts light energy into chemical energy stored in glucose, providing energy for organisms within the ecosystem. It also recycles carbon dioxide into oxygen, supporting life by replenishing oxygen in the atmosphere. Additionally, photosynthesis plays a crucial role in the cycling of nutrients such as carbon and oxygen through the ecosystem.

Ecological pyramids, such as pyramid of energy, biomass, or numbers, are used by ecologists to show the flow of energy or biomass between trophic levels in an ecosystem. They demonstrate the decrease in energy or biomass as you move up the food chain, with each higher trophic level supporting fewer individuals. These pyramids help illustrate the distribution of energy within an ecosystem and the importance of each trophic level in maintaining balance.

The formation of a new community within an existing community is typically known as "infill development" or "infilling." This process involves developing vacant or underused parcels of land within an established area, rather than expanding into greenfield or undeveloped areas. Infill development can help maximize land use efficiency and revitalize existing communities.
