WebSo then we could also say that this net primary productivity is equal to 2,000 grams per square meter per year times four kilocalories per gram, the grams cancel out, and then you multiply four times 2,000, that's going to be 8,000 kilocalories, kilocalories per square meter per year. That would be the net primary productivity, because that's ... WebNet Primary Productivity Definition. Net Primary Productivity or NPP can be defined as the rate of accumulation of biomass or energy. The energy utilised during metabolic processes such as respiration is excluded from gross productivity (GPP). NPP is calculated primarily by an increase in the biomass in a unit time per unit area.
