This reflects the concept of energy transfer in ecosystems, which is often represented by an energy pyramid. Only a small percentage of energy from one trophic level is transferred to the next, leading to less biomass at the higher levels (secondary and tertiary consumers) compared to the lower levels (producers and primary consumers).
