Detailed explanation-1: -Net Primary Production (NPP) = GPP – RA The amount of organic carbon produced by plants that is not consumed by their own respiration. It is the increase in the plant biomass in the absence of herbivores.

Detailed explanation-2: -GPP can be calculated by measuring the decrease in DO when put in the dark (only respiration (R) will occur) • NPP = GPP – R so GPP = NPP + R Page 32 Experiments to Calculate Productivity (Light/Dark Rxns) • You start a light bottle/dark bottle measurement on algae Species X with 10 mg/L of oxygen in both bottles.

Detailed explanation-3: -The overall productivity of a system can be found in an equation, where the Net Primary Production, or NPP, is equal to the Gross Primary Production, or GPP, minus the Carbon respiration, or R. The formula is the NPP = GPP-R. The NPP is the overall efficiency of the plants in the ecosystem.

Detailed explanation-4: ->The overall productivity of a system is often found in associate equations wherever information superhighway Primary Production, or NPP, is capable of Gross Primary Production, or GPP, minus the Respiration, or R. The formula is that the NPP = GPP-R.
