Net productivity ecology
Primary production is the synthesis of organic material from inorganic molecules. Primary production in most ecosystems is dominated by the process of photosynthesis, In which organisms synthesize organic molecules from sunlight, H2O, and CO2. Primary production is sometimes broken down into Net Primary Production (NPP) and Gross Primary Production (GPP). Gross primary production measures all carbon assimilated into organic molecules by primary producer… WebLearn about energy transfer in a food web, what biomass is and how it is measured, what GPP and NPP are, how to calculate them and the units you would use.Fo...
