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
Answer:
The Movement is called Migration.
Explanation:
Migration is an important component of Population growth. Migration is the movement of individual organisms into, or out of, a population.Migration affects population growth rate. Migration can be of two types- Immigration and Emigration. Immigration can be described as the movement of individual into a population from other areas. This increases the size of a population and helps in growth. Emigration can be described as the movement of individual out of population.
