Primary productivity can be affected by what

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. WebPhytoplankton growth is affected by the availability of nutrients and light, which in turn are affected by the structure of the upper water column. Large-scale changes to climate and oceanographic conditions can change the water column structure and thus lead to changes in phytoplankton growth and primary productivity.
