Definisjon
- "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. Calcite is a mineral that is a polymorph of calcium carbonate. The chemical formula of calcite is CaCO3. Standard names also exist for aragonite, another polymorph of calcium carbonate. 'Calcareous phytoplankton' are phytoplankton that produce calcite. Phytoplankton are autotrophic prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis.
