This question was addressed to me in final exam.

I'd like to ask this question from Ecological Pyramids in chapter Ecosystems of Energy Management

Answer 1

The correct answer is (a) Due to loss of energy between the trophic level

To explain: The pyramid shape of the trophic level comes from the loss of energy between the levels. The chain grows only 10% of the energy supply to the proceeding animals, that energy loss will be used to produce new primary consumers.
