The scientific name for the process of making energy from light is photosynthesis. This process occurs primarily in green plants, algae, and certain bacteria, converting light energy into chemical energy stored as glucose. In this process, chlorophyll absorbs sunlight and facilitates the reaction between carbon dioxide and water, resulting in the production of glucose and oxygen. Photosynthesis is fundamental to life on Earth, as it forms the basis of the food chain and contributes to the planet's oxygen supply.
