Which of the following ecological pyramids is generally inverted?
- APyramid of numbers in grassland
- BPyramid of energy
- CPyramid of biomass in a forest
- DPyramid of biomass in a sea
Solution & Step-by-step Explanation
[Image comparing upright and inverted pyramids of biomass]
Energy pyramids are always upright.
Biomass pyramids in most terrestrial ecosystems are upright.
Biomass pyramids in the sea are generally inverted because the biomass of primary producers (phytoplankton) at any given time is much less than the biomass of the consumers (zooplankton and fish) that depend on them.
