Text Solution

Verified by Experts

The correct Answer is:
A

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.
