Question

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

Answer 1

Well usually in any biological system there is heat loss, so your answer should be something like this; It decreases from one trophic level to another :)

Answer 2

A more specific response would be that 10% of the energy is transferred in each trophic level. So it would look a little like this.
