Question

Pyramid of energy is always upright, can never be inverted.

Answer 1

The pyramid of energy is always upright because energy decreases at each successive trophic level. Producers capture solar energy, which flows through the food chain but is lost as heat at each transfer, so energy available at higher levels is less. Thus, energy pyramids cannot be inverted as energy flow is unidirectional and always diminishes with each level. This consistent energy loss ensures that the energy pyramid is always upright, unlike pyramids of numbers or biomass, which can be inverted depending on the ecosystem.
