Which does the trophic structure of a community describe?
Trophic structure basically explains general feeding relationship between living things and the subsequent energy transfer. It's usually depicted in a pyramid form with several levels. Bottom level is the primary provider (producer), usually plants, and top level are usually occupied by predators. Energy is lost from transfer from one level to another (bottom to top).
Why are there only 3-5 trophic levels in an ecosystem?
There are only a few trophic levels in an ecosystem because as a trophic level consumes, it only reiceves 10% of the energy in the previous level. There are only few trophic levels because as the feeding levels continue (like grass --> rabbit --> hawk) energy is lost. Most of it, you learn, is lost through heat. By the time it gets to the top level, there just isn't enough energy to continue the food chain. (that's what that is). I know its hard to imagine that grass has more energy than a hawk but the grass gets energy from the sun which is a lot of energy. The person before did mention the 10% thing which is also true.
What the most energy efficient part of a trophic pyramid?
It is the part that has the least amount of energy in the trophic pyramid. An owl or skunk would be an example of this.
Why do different trophic levels have different amounts of energy?
Some energy transferred at each successive trophic level enters the environment as heat.
If the 1st trophic level has 10000 kilocalories of energy how much energy will be available for trophic levels 2-4?
One million calories .
What is an organism in a food chain that represents a feeding step in the passage of energy and materials through an ecosystem.?
It is a trophic level.Trophic Level.
Which group of organisms would most likely be represented in a food chain?
It is a trophic level.Trophic Level.
Why can each trophic level support only about one tenth the amount of the living tissue of the level below?
This is because energy is lost at each trophic level. The energy available to the next trophic level is about 10% of the energy of the previous trophic level.
Why is it that only part of the energy store in one tropics level is passed on to the next level?
Because every organism, upon consuming a resource, must expend some energy in order to digest/process that resource. Thus not all energy is passed from trophic level to trophic level.
Why can each trophic level support only about one tenth the amount of living tissue of the level below?
This is because energy is lost at each trophic level (from all the activity done by that level, e.g., running, climbing, fighting) . The energy available to the next trophic level is about 10% of the energy of the previous trophic level.

Of energy gained compare to the amount of energy lost as heat at the second through fourth trophic levels?
As you climb trophic levels the general amount of energy lost is 90% so you get about 1/10 of the energy that was consumed by the animal per trophic level.
Term for each step in the transfer of energy and matter within a food web?
Trophic level
Which term best describes energy transfer between trophic levels?
when energy is transferred to a higher trophic level some of the energy is trued into heat and is released
What are the dynamics of any ecosystem?
two major process 1 = cycling of nutrient 2= chemical energy (food)
What happens to the energy that is not passed through the trophic levels of an energy pyramid?
It used by the organisms at each trophic level to keep themselves alive.
