Answer:
The net annual primary productivity of a particular wetland ecosystem is found to be 8,000 kcal/m2. If respiration by the aquatic producers is 12,000 kcal/m2/year
Gross primary productivity in a region of tropical forest is 1,200 kcal/m-Tyr. In this ecosystem, producers are. 25% efficient. 16,000 kcal/m²/yr
