1.	Question : How are productivity, gross productivity, net primary productivity, and secondary productivity interrelated?
Answer» Solution :Productivity: It is the rate of production of biomass per unit area over a period of time by plants during photosynthesis. GROSS Productivity: It is the rate of production of organic matter by green plants per unit time per unit area. NET Primary Productivity: Net primary productivity is the AVAILABLE biomass for the consumption of heterotrophs. Net primary Productivity: Gross Primary Productivity-Respiratory losses, `N_(PP) = G_(PP) - R.` Secondary Productivity: It is the rate of formation of NEW organic matter by consumers.
