In: Biology

Answer 1

Basically burning calories, atp created by cellular respiration. We are warm blooded animals meaning we have to maintain a constant body temp to stay alive. We use most of the food we eat to give us calories for this energy. To do this we have to eat every day multiple times a day. Compared to a cold blooded animal like a snake or a fish their food intake is much lower relatively speaking.
