The net annual primary productivity of a particular wetland ecosystem is found to be 5,000 kcal/m2/yr. If respiration by the aquatic producers is 11,000 kcal/m2/yr, what is the gross annual primary productivity for this ecosystem, in kcal/m2/yr?

5,000 kcal/m2/yr
6,000 kcal/m2/yr
16,000 kcal/m2/yr
22,000 kcal/m2/yr

Answer:

For this ecosystem, the gross annual primary productivity is 16,000 kcal/m2/yr

Explanation:

gross [annual] primary productivity (GPP) = net [annual] primary productivity (NPP) + respiration (R)

GPP = 5,000 kcal/m2/yr + 11,000 kcal/m2/yr

GPP = 16,000 kcal/m2/yr
