<human>:  How do plants create food from light?
<bot>: Plants use a process called photosynthesis to create food from light. Photosynthesis is a process that converts light energy, usually from the sun, into chemical energy stored in the bonds of food molecules. During photosynthesis, plants use light energy to convert water and carbon dioxide into oxygen and glucose. The glucose is used as energy by the plant, while the oxygen is released into the atmosphere.
