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 marine environments, fish biomass (occupying higher trophic levels) can surpass that of phytoplankton (primary producers) owing to the phytoplankton's swift turnover rate. Consequently, an inverted biomass pyramid emerges, characterized by lower producer biomass compared to consumer biomass.
