A
Pyramid of biomass in sea is generally inverted.
Correct answer
B
Pyramid of biomass in sea is generally upright.
C

Solution

The pyramid of biomass and number may be upright or inverted. However, the pyramid of energy can never be inverted. The energy pyramid is always upright. The pyramid of biomass in the sea is generally inverted. This Inverted pyramid of biomass is due to the presence of a small standing crop of phytoplankton supporting a large standing crop of zooplankton.

Hence, the correct answer is option: 'B'.
