Productivity: It is the rate of production of biomass at any trophic level at any given interval of time.
Gross productivity: It is the rate of production of organic matter by green plants per unit time per unit area. In other words, it is the total amount of productivity.
Net primary productivity: It is the difference between gross primary productivity and the loss due to respiration. Net primary productivity is the difference between gross primary productivity and respiratory loss.
NPP = GPP - R
Secondary productivity is the rate of formation of organic matter by consumers.
