Question

As we move above up from one trophic level to another in an energy pyramid, what happens to the energy?


A. It decreases from one trophic level to another.

B. It remains the same for each trophic level.

C. It increases from one trophic level to another.

Answer 1

A, it decreases from one trophic level to another.
The general rule of thumb is that only 10% of the energy is passed on. Lets say that a fish eats plankton, and then you eat the fish. As each step goes up, less and less of the original energy from the plankton is absorbed
