An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.The energy in an energy pyramid is measured in units of kilocalories (kcal).Energy ... Living systems also follow the law of conservation of energy.rophic level: energy flow and trophic levels. The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
