It principally occurs through the process of photosynthesis which uses light as its source of energy but it also occurs through chemosynthesis which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Agriculture is one of the industries that makes up the primary sector. Primary productivity in ecology the rate at which energy is converted to organic substances by photosynthetic producers photoautotrophs which obtain energy and nutrients by harnessing sunlight and chemosynthetic producers chemoautotrophs which obtain chemical energy through oxidation.

The primary production of phytoplankton has been estimated for decades by the 14 C Steemann-Nielsen 1952 and O 2 Gaarder and Gran 1927 methodsEven though the majority of the scientific community uses the 14 C method there have been others that have used the O 2 method as an alternative especially in developing countries eg.
