Detailed explanation-1: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-2: -The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Detailed explanation-3: -The leaves of green plants contain chlorophyll, which absorbs sunlight for producing food. This food is then used by the plant itself as well as other animals, including humans.
