How do you calculate net primary productivity

WebNov 30, 2024 · Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. Net primary production is directly related to ecosystem conditions.
