That's really thniikng at a high level
so that we keep warm and get energy.
To provide the energy needed to move muscles, to keep itself warm and to drive endothermic chemical, cellular processes.

Food provides our energy source - energy is needed to extract the oxygen from the atmosphere and diffuse it into our bloodstream. As warm blooded animals we can only digest food and function if our bodies are at 37C - energy is required for this. We need energy to move our muscles which also only operate when they are warm
Reptiles can't keep warm all by themselves. They are ectothermic which meens they are cold blooded. That meens that they need the sun or somthing elses heat to keep warm. Whatever their surrounding climates temperature is is what the reptiles temperature is. They will lose energy and may die in the cold.
