Question

The net annual primary productivity of a particular wetland ecosystem is found to be 6,000 kcal/m2/yr. If respiration by the aquatic producers is 10,000 kcal/m2/yr, what is the gross annual primary productivity for this ecosystem, in kcal/m2/yr? 4,000 kcal/m2/yr 6,000 kcal/m2/yr 10,000 kcal/m2/yr 16,000 kcal/m2/yr

Answer 1

Gross annual primary productivity = 16,000 kcal/m²/yr

Step-by-step explanation:

Given:

Net annual primary productivity on wetland = 6,000 kcal/m²/yr

Respiration by aquatic producers = 10,000 kcal/m²/yr

Find:

Gross annual primary productivity

Computation:

Gross annual primary productivity = Net annual primary productivity on wetland + Respiration by aquatic producers

Gross annual primary productivity = 6,000 kcal/m²/yr + 10,000 kcal/m²/yr

Gross annual primary productivity = 16,000 kcal/m²/yr
