<span>The amount of energy at each trophic level decreases as itmoves through an ecosystem. ... An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, levelto the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.</span>
Kinetic energy is best described as the energy of motion, energy of position, or the energy of electrical change.
