Definition

  • "Productivity of carbon" refers to the production of biomass expressed as the mass of carbon which it contains. "Productivity" means production per unit area. Net primary productivity is the excess of gross primary productivity of organic carbon (the rate of synthesis of biomass from inorganic precursors) by autotrophs ("producers"), for example, photosynthesis in phytoplankton, over the rate at which the autotrophs themselves respire some of this biomass. In ocean modelling, diazotrophs are phytoplankton of the phylum cyanobacteria distinct from other phytoplankton groups in their ability to fix nitrogen gas in addition to nitrate and ammonium. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis.
