Question

A wetland ecosystem has an NPP of 1.02 kg C/m2/year and a GPP of 2.80 kg C/m2/year. How much carbon is being used during respiration of autotrophs?

a) 3.82 kg C/m2/year
b) 1.76 kg C/m2/year
c) 1.78 kg C/m2/year
d) 2.86 kg C/m2/year
e) 2.75 kg C/m2/year

Answer 1

The carbon being used during respiration of autotrophs is 1.78 kg C/m2/year.

Step-by-step explanation:

The carbon being used during respiration of autotrophs can be calculated by subtracting the NPP from the GPP. In this case, the carbon being used during respiration is 2.80 kg C/m2/year - 1.02 kg C/m2/year = 1.78 kg C/m2/year.
