Ecological pyramids represent the relationship between the organisms at different trophic levels and they are generally inverted for :
- A Pyramid of number in grassland
- B Pyramid of energy in pond ecosystem
- C Pyramid of biomass in grassland
- D Pyramid of biomass in sea
Answer & Solution
Correct Answer
(D) Pyramid of biomass in sea
Step-by-step Solution
Detailed explanation
(D) Pyramid of biomass in sea
The pyramid of biomass in a sea or aquatic ecosystem is generally inverted because the biomass of fishes (primary and secondary consumers) far exceeds that of phytoplankton (producers).
The pyramid of number in a grassland is upright.
The pyramid of energy is always upright in all ecosystems because energy is lost as heat at each trophic level.
The pyramid of biomass in a grassland is upright.
