Answer:
<em>Digested food is a source of potential energy</em>
Explanation:
When we digest food, the molecules of the food are broken down into smaller compounds. Chemical energy is released due to this process. Chemical energy can be used to form glucose and fat. These molecules store energy in them. When energy is required by the body, the glucose molecules can be converted into ATP and hence give energy. This energy can be used for various purposes such as it can be converted into mechanical energy for muscle movements.
