(iv) A is zooplanktons and B is phytoplanktons.

Options

A. I and iv
B. ii and iii
C. I and iii
D. ii and iv

Answer

C

Explanation

The given pyramid represents pyramid of biomass in an aquatic ecosystem. In this pyramid, biomass of phytoplanktons, i.e., producers (represented by A ) is smaller than that of zooplanktons, i.e., primary consumers ( represented by B). Phytoplanktons support zooplanktons as the latter feed upon them.
