MP Board · Class 12 · Biology · EcosystemWhich of the following correct mathematical equations represents Net Primary Productivity (NPP)?
Step-by-Step Solution
Net Primary Productivity (NPP) is the total organic matter stored by green plants after subtracting the energy lost through respiration (R). Thus, NPP = GPP - R, where GPP is Gross Primary Productivity.
