Question

During the daylight hours, a field of plants in the Midwest has a gross primary productivity value of 22 gC/m2 / day. During the roughly 12 hours of the night, the plants use about 6.6 gC/m2 /day. What is the net primary productivity of this field?

Answer 1

The net primary productivity of the field is 15.4 gC/m2/day.

Step-by-step explanation:

The net primary productivity of the field can be calculated by subtracting the amount of carbon used during cellular respiration from the gross primary productivity. In this case, the gross primary productivity is 22 gC/m2/day and the amount used during cellular respiration is 6.6 gC/m2/day. To find the net primary productivity, subtract the amount used during cellular respiration from the gross primary productivity: 22 gC/m2/day - 6.6 gC/m2/day = 15.4 gC/m2/day.

Answer 2

The net primary productivity of the field is 15.4 gC/m₂/day.

Step-by-step explanation:

The net primary productivity of the field can be calculated by subtracting the amount of carbon used during cellular respiration from the gross primary productivity. In this case, the gross primary productivity is 22 gC/m2/day and the amount used during cellular respiration is 6.6 gC/m₂/day. Therefore, the net primary productivity of the field is 15.4 gC/m₂/day.
