Question

The pyramid of biomass in the sea is generally inverted because in the sea:

• A. Biomass of fishes exceeds that of phytoplankton.
• B. Number of phytoplanktons is more.
• C. Number of phytoplanktons is less.
• D. Large fishes feed on small fishes.

Hint:

In ecosystems like the sea, the biomass pyramid can be inverted because the rapid turnover of small producers (phytoplankton) supports a large biomass of consumers (fishes).

Answer 1

The Correct Option is A

In the marine ecosystem, the biomass of fishes (which form the higher trophic levels) can exceed the biomass of phytoplankton (the primary producers) due to the rapid turnover rate of phytoplankton. This results in an inverted pyramid of biomass, where the primary producers have less biomass than the consumers.
