The energy pyramid being referred to is in the attachment below.

Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
