Ecological pyramids represent the relationship between the organisms at different trophic levels and they are generally inverted for :

Options

  1. APyramid of number in grassland
  2. BPyramid of energy in pond ecosystem
  3. CPyramid of biomass in grassland
  4. DPyramid of biomass in sea

Correct answer

D. Pyramid of biomass in sea

Step-by-step solution

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. Answer: Pyramid of biomass in sea
