Description:

An energy pyramid is a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain. From the bottom-up, they are as follows:
Producers — bring energy from nonliving sources into the community
Primary consumers — eat the producers, which makes them herbivores in most communities
Secondary consumers — eat the primary consumers, which makes them carnivores
Tertiary consumers — eat the secondary consumers
