Definition
A graphical representation in the form of a pyramid showing the feeding relationship and the number of organisms at each trophic level.
Supplement
The pyramidal shape indicates that the number of organisms or species is largest at the bottom, and is narrowing towards the apex. The Pyramid of Numbers can be used to determine how the population of a particular species can affect another. It can also serve as a basis for the quantitative analysis of an ecosystem.
