Answer:
D.20,000
Explanation:
The Gross Annual Primary Productivity for the wetland ecosystem is the amount of carbon taken up by the aquatic producers through photosynthesis.
Given that: Net Annual Primary Producer is 8,000 kcal/m2 per year, and respiration by the aquatic producers is 12,000 kcal/m2 per year, using the formula NPP = GPP – Respiration, we can determine the Gross Annual Primary Productivity of the wetland ecosystem.
NNP = 8,000 kcal/m2
Respiration = 12,000 kcal/m2
GPP = x
8,000 = x – 12,000 (NPP = GPP – Respiration)
Solve for x:
x = 8,000 + 12,000
x = 20,000 kcal/m2 per year
GPP = 20,000 kcal/m2 per year
I believe the answer is littoral zones.
Sorry if I'm wrong, Hope this helps.

The Yellowstone River ecosystem can support 2,300 bald eagles. This is an example of<u> temperate- zone ecosystems</u>
Explanation:
Yellowstone National Park is a natural paradise with over 70 species of birds,which include trumpeter swans, sandhill cranes, loons, peregrine falcons, osprey and bald eagles
The Greater Yellowstone Ecosystem, with Yellowstone at its core, is one of the largest nearly intact temperate- zone ecosystems on Earth. It has an area of 12–22 million acres; 18,750– 34,375 square miles
<u>Temperate ecosystems are the ecosystem that are characterized by the seasonality in temperature, with cooler winters and warmer summers, and also show various seasonality in precipitation patterns, resulting from seasonal changes in the orientation of Earth's axis relative to the sun.</u>
