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

Answer:

New GPP $= 264000$ kcal/m2

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 -

$22000 + \frac{20}{100} * 22000\\22000 + 4400\\26400$

New GPP $= 264000$ kcal/m2
