Question

Given below is a pyramid found in an ecosystem, where each bar represents the standing crop available in the trophic level.

Identify the kind of pyramid and with the help of an example explain the conditions where this kind of pyramid is possible in nature.

Answer 1

Inverted pyramid of biomass (standing crop). It occurs in aquatic ecosystems, e.g., phytoplankton (producers) have a low standing crop but very high turnover, while consumers (zooplankton/fish) have greater accumulated biomass, so the biomass pyramid is inverted.
