Answer:
New GPP [tex]= 264000[/tex] kcal/m2
Explanation:
Given -
Number of new trees planted [tex]= 400[/tex]
Before planting new trees, the gross annual primary productivity of a particular wetland ecosystem [tex]= 22,000[/tex] kcal/m2
The increase in gross primary productivity [tex]= 20[/tex] %
The new GPP will be equal to
Existing GPP + [tex]20[/tex] % of Existing GPP
Substituting the given values, we get -
[tex]22000 + \frac{20}{100} * 22000\\22000 + 4400\\26400[/tex]
New GPP [tex]= 264000[/tex] kcal/m2
