productivity - productivity
productivity - (Of an ecosystem), primary productivity is the rate at which energy from light is absorbed and utilized with carbon dioxide in the production of organic matter in photosynthesis. Net productivity is given by the amount of organic matter formed in excess of that used in respiration. It represents food potentially available to the consumers of the ecosystem. It can be measured approximately by sampling vegetation at intervals and measuring the dry weight produced per unit area; or on a small scale in appropriate conditions by measuring rates of photosynthesis and respiration of whole plants or of small areas of vegetation.
