Read the statements and select the correct option Statement 1: In an aquatic ecosystem, pyramid of biomass is inverted.
Statement 2: Biomass depends upon reproductive potential and longevity of individuals.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statement 1 and 2 are incorrect.

Answer

A

Explanation

In a marine aquatic ecosystem, the biomass of phytoplanktons (producers) is smaller than that of zoolplanktons (primary consumers) and the biomass of zooplanktons is smaller than that of secodary consumers. This results in the inverted pyramid of biomass in an aquatic ecosystem. This shape is the consequence of the very short life spans of phytoplanktons, which are consumed almost as rapidly as they are formed. Also phytoplanktons have high reproductive potential, i.e., they reproduce rapidly.
