Plants perform photosynthesis, which is the process by which they produce their own food from sunlight, carbon dioxide, and water. Through photosynthesis, plants take in carbon dioxide and water and produce glucose and oxygen. The glucose is used by the plant as an energy source or food, while oxygen is released as a byproduct into the atmosphere. This process is essential as it provides food for plants and oxygen for animals and people, and plays an important role in the ecosystem.

Glucose + Oxygen
Plants take in carbon dioxide
and water and produce glucose
(a sugar) and oxygen.
