! NPP represents the organic matter that
is available as food for other
organisms. ! In terrestrial environments NPP is often
estimated by measuring aboveground
biomass, the total mass of living
plants, excluding roots. ! On land, photosynthesis and plant growth are maximized when
temperatures are warm and conditions
are wet; conversely, photosynthesis
cannot occur efficiently at low
temperatures or under drought stress. Tropical Wet Forests (Rain forests)
