NEET Botany Ecosystem Components MCQ Question
If the gross primary productivity (GPP) of an ecosystem is 5000 kcal m2 yr1 and the respiration losses (R) are 2000 kcal m2 yr1, what is the net primary productivity (NPP)?
3000 kcal m2 yr1
7000 kcal m2 yr1
2000 kcal m2 yr1
5000 kcal m2 yr1
Correct Answer
Detailed Explanation
Net primary productivity (NPP) is calculated as GPP minus respiration losses (R). Here, NPP = 5000 - 2000 = 3000 kcal m2 yr1.
