Primary production is the synthesis of new organic material from inorganic molecules such as H2O and CO2. It is dominated by the process of photosynthesis which uses sunlight to synthesise organic molecules such as sugars, although chemosynthesis represents a small fraction of primary production. Organisms responsible for primary production include land plants, marine algae and some bacteria (including cyanobacteria).
