ecological pyramid


Show Summary Details

Quick Reference

Graphical representation of the trophic structure and function of an ecosystem. The first trophic level, of producer organisms (usually green plants), forms the base of the pyramid, with succeeding levels added above to the apex. There are three types of pyramids: of numbers, of biomass, and of energy. The alternative name for the concept is taken from the name of Dr Charles Elton, FRS, the British ecologist who devised it.
