Answer: 1.4 kg C/m2/year
Explanation:
Given that,
Gross Primary Production (GPP) = 3.8 kg C/m2/year
Rate of cellular respiration (R) = 2.4 kg C/m2/year
The NPP is equal to the Gross Primary Production (GPP) minus Rate of cellular respiration.
Net Primary Production (NPP):
= Gross Primary Production - Rate of cellular respiration
= 3.8 kg C/m2/year - 2.4 kg C/m2/year
= 1.4 kg C/m2/year
The NPP is the overall efficiency of the plants in the ecosystem.
