Question

a valley in the rocky mountains has an annual net primary productivity of 1,320 kg c / m²/year, and the energy needed by the producers for their own respiration is 1,980 kg c / m²/year. what is the gross primary productivity of this valley? kg c / m²/year

Explanation:

Step1: Recall the formula

Gross primary productivity (GPP) = Net primary productivity (NPP) + Respiration (R)

Step2: Substitute values

GPP = 1320 + 1980

Step3: Calculate result

GPP = 3300

Answer:

3300
