Every population needs energy to survive. That energy comes from the sun. Everything in the food chain or food web relies on the sun for that energy and obtains it throughout the chain. A person can feel the sun warming the skin. A field mouse and a hawk can feel it, too. Neither of them can directly use the sun's energy; however, they must have it in order to breathe, keep their hearts beating, and to stay alive. What is the importance of energy for living organisms?
