Before a group of volunteers planted 400 mangrove trees, the gross annual primary productivity of a particular wetland ecosystem is found to be 22,000 kcal/m2 . The trees have increased the gross primary productivity by 20%. What is the new GPP of the wetland?

New GPP kcal/m2

Explanation:

Given -

Number of new trees planted

Before planting new trees, the gross annual primary productivity of a particular wetland ecosystem kcal/m2

The increase in gross primary productivity   %

The new GPP will  be equal to

Existing GPP + % of Existing GPP

Substituting the given values, we get -

New GPP kcal/m2
