The dietary compound has energy stored in their bonds as chemical energy.

So, from sun human consume chemical energy which is stored in food.

The energy even if consumed by eating meat is also chemical energy which is stored as potential energy.

The breakdown of food or chemical energy into monomers leads to release of thermal energy or heat to maintain optimum body temperature.

Chemical energy also gets converted to mechanical energy which allows functioning of vital organs and movement of body.
