Solution
Net Primary Productivity (NPP) is the weight of organic matter stored by producers in a unit area/volume per unit time. NPP is equal to the rate of organic matter created by photosynthesis minus the rate of respiration and other loses. Stored biomass is transferred from one trophic level to another trophic level. Secondary Productivity is the rate of energy storage at consumers levels-herbivores, carnivorous and decomposers.
Gross Primary Productivity (GPP) is referred as total rate of photosynthesis including the organic matter used up in respiration during the measurement period.
