Phototrophic organisms convert light energy into chemical energy in the form of ATP. Photosynthetic organisms (photoautotrophs) also use light energy to make both ATP and reduced electron carriers (NADH or NADPH), which are both required to reduce carbon dioxide (CO2) to carbohydrate (CH2O).
Photosynthesis is the conversion of carbon dioxide and water into carbohydrates using energy from sunlight. It is the main process by which new energy becomes available to life on Earth. Plants and algae use photosynthesis to convert light energy into a form available to other organisms, and thus form the base of almost every food chain.
