What kind of pyramid is represented by the given figure?

Options

A. Pyramid of numbers in a forest ecosystem.
B. Pyramid of numbers in a parasitic food chain.
C. Pyramid of biomass in a forest ecosystem.
D. It is a wrong pyramid.

Answer

C

Explanation

Pyramids of biomass are comparatively more fundamental, as they, instead of geometric factor, show the quantitative relationships of the standing crops. In grassland and forest, there is generally a gradual decrease in biomass of organisms at successive levels from the producers to the top carnivores. Thus, pyramids of biomass and number are upright in terrestrial ecosystems.
