MP Board · Class 12 · Biology · EcosystemWhich ecological pyramid is ALWAYS upright in any ecosystem and can never be inverted?
Step-by-Step Solution
Pyramid of energy is always upright, because when energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step (10% law). Therefore, energy at a higher trophic level is always less than at a lower level.
