How do animals get energy from food?
Animals obtain energy from the food they consume, using that energy to maintain body temperature and perform other metabolic functions. Glucose, found in the food animals eat, is broken down during the process of cellular respiration into an energy source called ATP.
What gives animals the energy they need to survive?
In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal’s home (habitat) must provide these basic needs (air, water and food) along with shelter from bad weather and predators.

Why do we organisms need energy?
All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments; metabolism is the set of the processes that makes energy available for cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy.
