Question

Select the incorrect statement for productivity in the ecosystem.

• A. GPP is rate of production of organic matter by producers during photosynthesis per unit time and area
• B. NPP is less than GPP
• C. GPP is available biomass for consumption to heterotrophs
• D. NPP is rate of organic matter stored by producers in excess of respiratory loss

Answer 1

The correct option is C GPP is available biomass for consumption to heterotrophs

NPP = GPP – R and it is available biomass for consumption to herbivores.
NPP is less than GPP.
