Question

Which of the following statement is incorrect regarding ecological pyramids?

• A. The pyramid of energy is inverted in ocean ecosystem.
• B. The pyramid of biomass is inverted in aquatic ecosystem.
• C. The pyramid of numbers is upright in a grassland ecosystem.
• D. The pyramid of biomass is upright in a grassland ecosystem.

Answer 1

The correct option is A The pyramid of energy is inverted in ocean ecosystem.

The pyramid of energy is always upright irrespective of the type of ecosystem, because energy decreases from a lower trophic level to a higher trophic level. Pyramid of biomass and pyramid of number vary in structure depending on the type of ecosystem. For example, pyramid of biomass is inverted in an aquatic ecosystem but pyramid of biomass is upright in a terrestrial ecosystem.
