Web2 nov. 2016 · Net Primary Productivity (NPP) is the total amount of energy converted from solar energy to chemical energy with the subtraction of the energy used for respiration. Net Primary Productivity is affected by temperature, water availability, carbon dioxide, and nutrients, all of which are abiotic factors. In Tropical Rainforests, water, sunlight ... Web• GPP vs. NPP vs. NEP vs. NECB vs. NBP vs. NEE – But what about fluxes of C other than R ecosyst? • leaching, lateral transfers, VOCs, and disturbances • DICs and DOCs • Time scales of decades to centuries – NEP = GPP - R ecosystem (or NPP - R hetero) ≠ NEP = (NPP - R heterotr) ± F lateral - (F disturb + F leach + F emiss + F CH4)
