The process that plants use to convert energy from the Sun into chemical energy.

The process that plants use to convert energy from the Sun into chemical energy. Inside chloroplasts, carbon dioxide and water react in the presence of sunlight to form sugars and oxygen. Photosynthesis is essential to all ecosystems, converting the Sun's energy into usable chemical energy that can then pass further up the food chain, and regulating levels of carbon dioxide and oxygen in the atmosphere.
