Answer: 1.4 kg C/m2/year

Step-by-step 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.
