Question

if gpp = 5000 kcal/m²/year and respiration = 2000 kcal/m²/year, what is npp?

Explanation:

Step1: Recall the formula for NPP

Net - Primary Production (NPP) is calculated by the formula $NPP = GPP - R$, where $GPP$ is Gross Primary Production and $R$ is respiration.

Step2: Substitute the given values

Given $GPP = 5000\ kcal/m^{2}/year$ and $R = 2000\ kcal/m^{2}/year$. Then $NPP=5000 - 2000$.

Step3: Calculate the result

$NPP = 3000\ kcal/m^{2}/year$.

Answer:

3000
