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

Explanation:
The ball-and-stick model cannot show the actual size of the atoms depicted in the model. You also cannot see the actual bond lengths between the atoms.
<span>Research partitioning is an adaptive evolution that when
species are have similar preys, they compete with each other and one species is
deemed to extinct in the process however if two species are of different preys,
then they can exist with one another. To exist with one another, organisms
belonging to a same species either compete for the resources or divide it
amongst themselves. This concept is important because it helps in diversified
ecology, where animals and plants of the same species co-exist and creates a
beauty with nature.</span>
