"\"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. 'Miscellaneous phytoplankton' are all those phytoplankton that are not diatoms, diazotrophs, calcareous phytoplankton, picophytoplankton or other seperately named components of the phytoplankton population. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis."@en . "true" . "SDN:P07::CF14N50" . . . . .
