WebFalse: Nutrient export is likely to decline. Pose an argument to explain how the increase of CO2 in the atmosphere from the burning of fossil fuels could either increase or decrease the primary productivity of Amazon forests. Elevated CO2 in the atmosphere could stimulate tree growth because more carbon is available for photosynthesis. WebNov 2, 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 ...
