Biomass Pyramid

Definition

noun

A graphical representation to show the relative amounts of biomass at each trophic level.


Supplement

Biomass pyramids are shaped that way to show that biomass is largest at the base, and decreasing in amount as it goes through the apex. The two types of biomass pyramids are the upright and the inverted. The upright pyramid is found in most ecosystems. It results when the combined weight of producers is larger than the combined weight of consumers. An inverted type results when the combined weight of producers is smaller than the combined weight of consumers.


Synonym: Ecological Pyramid of Biomass.
Compare: Energy Pyramid.
See also: Ecological Pyramid, biomass.
