A forest ecosystem can support a limited number of bears. This is because available energy is lost from one trophic level to the next. (flies, trout, then bears)

Answer:

The correct answer would be C)  available energy is lost from one trophic level to the next.  

It is the universal law that the energy is lost when transferred from one trophic level to the next.

It is because most of the energy present at any trophic level is used by the organisms for their biological processes such as locomotion, reproduction et cetera. Due to this, most of the energy is lost as heat in the surrounding environment.

In the given food chain, the bears are present at the highest trophic level and thus they would get minimum energy.  

Thus, the ecosystem can provide only a limited amount of energy to the bears due to which the ecosystem can support a limited number of bears.
