What type of energy is stored in food?

Food contains chemical energy, which is the energy stored in the bonds of the nutrients that make up the food, such as carbohydrates, fats, and proteins. When we consume food, our bodies break down these nutrients through processes such as digestion and metabolism, releasing the stored energy that can be used for various bodily functions, such as growth, movement, and maintaining body temperature.

This type of energy is fundamental to the functioning of living organisms, as it drives all biological processes. Other forms of energy listed, like light energy, kinetic energy, and electrical energy, are not stored in food. Light energy refers to the energy from sunlight, kinetic energy is related to the motion of objects, and electrical energy involves the movement of electrons through a conductor. These forms of energy are different from the chemical energy that is specifically found in food.
