WebFeb 25, 2024 · Tropical forests cover only 13% of the earth’s land surface but may account for one-third of terrestrial net primary productivity (NPP) (Del Grosso 2008) and store 40–50% of the terrestrial biomass carbon (Houghton 2005; Lewis et al. 2009).Climate change has the potential to reduce the forests’ sink strength for carbon (C) in a hotter … WebSo then we could also say that this net primary productivity is equal to 2,000 grams per square meter per year times four kilocalories per gram, the grams cancel out, and then you multiply four times 2,000, that's going to be 8,000 kilocalories, kilocalories per square meter per year. That would be the net primary productivity, because that's ...
