Vedclass · Answer

(C) In an ecosystem,the rate of synthesis of organic matter by producers is called Primary Productivity. Gross Primary Productivity $(GPP)$ is the total amount of energy fixed by producers through photosynthesis. Net Primary Productivity $(NPP)$ is the energy remaining after the respiratory losses of producers $(NPP = GPP - R)$. Secondary Productivity is the rate of formation of new organic matter by consumers (like a grasshopper). Since a grasshopper is a primary consumer,the energy available to it for its growth and biomass accumulation is termed as Secondary Productivity.

Which of the following represents the amount of energy available to a grasshopper in a food chain?
