A primary producer, also known as an autotroph, is an organism at the bottom of the food chain that is responsible for synthesising organic compounds from carbon dioxide (CO2) through the process of photosynthesis. In terrestrial eco-regions (large units of land or water with distinct environmental conditions), these are mainly plants, while in aquatic eco-regions algae are predominant in this role.

Almost all life on Earth relies on primary production.
