Question

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?

Answer 1

New GPP
`= 264000` kcal/m2

Step-by-step explanation:

Given -

Number of new trees planted
`= 400`

Before planting new trees, the gross annual primary productivity of a particular wetland ecosystem
`= 22,000` kcal/m2

The increase in gross primary productivity
`= 20` %

The new GPP will be equal to

Existing GPP +
`20` % of Existing GPP

Substituting the given values, we get -

`22000 + (20)/(100) * 22000\\22000 + 4400\\26400`

New GPP
`= 264000` kcal/m2
