Terrestrial Primary Production: Fuel for Life - Nature

WebGross Primary Productivity refers to total productivity, while NPP (Net Primary Product) is simply net productivity. NPP (Net Primary Product) is calculated using GPP (Gross Primary Production), which means GPP has the ability to affect NPP. However, for Gross Primary Production, Net Primary Product does not have any effect on GPP at all. WebNPP is the net carbon gain by plants. It is the balance between the carbon gained by gross primary production (GPP – i.e., net photosynthesis measured at the ecosystem scale) and carbon released by plant mitochondrial respiration, both expressed per unit land area.
