Explanation:

Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.

The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).

The following statements refer to a pyramid of energy;

I. Some material is not assimilated by each trophic level.
