how did the food we eat gets converted into a chemical energy?.
Energy is stored in the bonds of the molecules that make up food. When we eat the food, the large molecules are broken down into smaller molecules that can be used by the cells of the body. The process of breaking down and using the food by our cells is called respiration. During respiration, the chemical energy is converted to heat, kinetic energy, and other forms of chemical energy, like that stored in the fat cells in our body.
 To be more specific,  chemical energy is contained in the bonds of the molecules of the food that we eat. Each nutritional element of a piece of food that is good for us is grown or created and energy is contained within those molecules. E g :A piece of fruit in the refrigerator would be a form of chemical energy in its potential energy state. Once we take the piece of fruit from the refrigerator and bite  it, the chemical energy once stored as potential energy then becomes kinetic energy.

As we ingest the piece of fruit, the stored chemical energy becomes kinetic energy as our body breaks down the bonds and begins to take what we need from the food that we are eating. The cells of our body then take this chemical energy and use it for their own needs to keep us healthy and happy. This type of chemical energy in motion is called respiration.
