As you move up the food chain, the number of organisms and the amount of energy typically do what?

Explanation:
Energy moves through a food chain, and most of it is used by organisms for life processes or lost as heat. Only a small portion passes to the next level, so less energy is available to support organisms higher up. Because energy is limited, there are many producers, fewer herbivores, and even fewer carnivores. So as you move up the chain, the number of organisms and the energy available typically decrease. Real ecosystems can vary, but the general pattern is a decrease.
