Producer

Photosynthetic organisms produce the biomass that supports food chains and life on Earth. They are called producers because they synthesise — make — biological molecules rather than obtaining them by eating other organisms.

Plants and algae are photosynthetic organisms: they use light energy to make glucose, a carbohydrate, from carbon dioxide and water. They are the main producers of food in ecosystems. Rather than obtaining their food by eating other organisms, they manufacture it themselves.
