Gross primary production is the rate of synthesis of biomass from inorganic precursors by autotrophs (\'producers\'), for example, photosynthesis in plants or phytoplankton. The producers also respire some of this biomass and the difference is \'net_primary_production\'. \'Productivity\' means production per unit area. The phrase \'expressed_as\' is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A." ;
