Question

Which ecological pyramid can never occur in an inverted form?

• A. Pyramid of number
• B. Pyramid of biomass
• C. Pyramid of energy
• D. Pyramid of species richess

Answer 1

Answer: (C)

Pyramid of energy

Pyramid of energy is always upright, can never be inverted because energy always flows from a particular trophic level to the next trophic level. The number of trophic levels in the grazing food chain is thus restricted as the transfer of energy follows 10 percent law only, according to which, 10 percent of the energy is transferred to each trophic level from the lower trophic level.
