food and water. :)
Animals eat food and absorb the vitamins, nutrients and energy and produce waste from the materials the body does not need. The bodies of dead animals also decay and produce waste.
All animals need protein because their bodies use the protein to produce energy. Without protein, animals would not be able to create the cellular reactions that sustain life.
Animals need food to stay alive because food gives them nutrients and energy. Nutrients and energy are both important because they help the bodies of animals function.
Animals need to breathe to get oxygen. Oxygen burns the food within their bodies and releases energy for various activities.
oxygen is needed to produce energy from food
The energy source is the sun. Plants use solar energy to produce the foods they need for growth. Animals feed on the plants or feed on animals that eat plants.
Food supplies the energy and material that animals need to grow, develop, and repair their bodies

No, cold blooded animals cannot survive without heat energy because their bodies need to heat up so they can do things like moving and eating. If an animal didn't heat their bodies up, they would die.
Our bodies need fat to porvide energy and to get all the vitamins we need.
Because the heavier an object is, the more force is required to lift it off the ground. So, by having light bodies, animals that can fly reduce the amount of energy they need to use to be able to fly.
Energy and protein. Cows need the energy for their bodies to produce milk and to keep them healthy. They are able to digest grass in their rumens to get the protein and energy for them that can be found in milk.
