Question

during the daylight hours, a field of plants in the midwest has a gross primary productivity value of 22 g c / m²/day. during the roughly 12 hours of the night, the plants use about 6.6 g c / m²/day. what is the net primary productivity of this field? g c / m²/day

Explanation:

Step1: Recall the formula for net primary productivity

Net primary productivity (NPP) = Gross primary productivity (GPP) - Respiration rate (R)

Step2: Identify the given values

GPP = 22 g C/m²/day, R = 6.6 g C/m²/day

Step3: Calculate the net primary productivity

NPP=22 - 6.6
NPP = 15.4 g C/m²/day

Answer:

15.4 g C/m²/day
