The energy pyramid is a diagram that shows the amount of energy at each trophic level in a food chain or web. The bottom of the pyramid represents the primary producers, which are organisms that make their own food from inorganic matter. The next level up represents the primary consumers, which are organisms that eat the primary producers. The tertiary consumers are the organisms that eat the primary consumers, and so on.
The cheetah is a carnivorous mammal that preys on gazelles, impalas, and other hoofed animals. As a tertiary consumer, the cheetah is at the top of the food chain and has few natural predators.
