In the equation GPP - R = NPP
GPP is Gross Primary Productivity
NPP is Net Primary Productivity
R here is :
Options
- AReproductive allocation
- BPhotosynthetically active radiation
- CRespiratory quotient
- DRespiratory loss
Correct answer
D. Respiratory loss
Step-by-step solution
Gross primary productivity of an ecosystem is the rate of production of organic matter during photosynthesis. A considerable amount of GPP is utilised by plants in respiration. Gross primary productivity minus respiration losses (R), is the net primary productivity (NPP).
The Net primary productivity (NPP) is the available biomass for the consumption to heterotroph (herbivores and decomposers).
