Where is most energy found in a standard food pyramid?

Explanation:
Energy in ecosystems begins with the sun and is captured by producers at the base of the food pyramid. Plants store that solar energy as chemical energy, forming the largest reservoir of usable energy in the system. When energy moves up to herbivores and then to predators, only a portion is passed along—roughly about 10% at each step—while the rest is lost as heat through metabolism, movement, digestion, and waste. Because energy is lost at every transfer, the available energy diminishes as you go higher, making the base the place with the most energy.
