NEET Botany Ecosystem Components MCQ Question
If the Gross Primary Productivity (GPP) of an ecosystem is 2000 kcal m2 yr1 and the respiration loss (R) is 500 kcal m2 yr1, what is the Net Primary Productivity (NPP) of this ecosystem?
1500 kcal m2 yr1
2500 kcal m2 yr1
500 kcal m2 yr1
2000 kcal m2 yr1
Correct Answer
Detailed Explanation
Net Primary Productivity (NPP) is calculated as Gross Primary Productivity (GPP) minus respiration losses (R). Therefore, NPP = 2000 kcal m2 yr1 - 500 kcal m2 yr1 = 1500 kcal m2 yr1.
