Vegetation Primary Productivity

Vegetation primary productivity is represented by the amount of carbon dioxide (CO2) fixed by photosynthesis, the process by which plants use sunlight energy to produce organic compounds from CO2 and water. Vegetation primary productivity is commonly split into gross primary productivity (GPP) and net primary productivity (NPP). GPP is the overall rate of carbon (C) fixed in the process of photosynthesis minus the C lost by photorespiration in …
