Recognise the figure and find out the correct matching according to pyramid of biomass in an aquatic ecosystem.

• A. a$-11$, b$-1.5$
• B. a$-11$, b$-4$
• C. a$-12$, b$-4$
• D. a$-21$, b$-4$

Answer 1

The given pyramid represents a pyramid of biomass in an aquatic ecosystem.
It is inverted in shape because the standing crop (biomass) of phytoplankton (primary producers) is smaller than that of zooplankton (primary consumers).
Case-specific solution
According to the given options, the more considerable value is a$-21$ and b$-4$.
Final answer
(D) a$-21$, b$-4$
