The net primary productivity for a temperate forest was measured as 2,000 mg c/m2/day. the respiratory rate of the community was determined to be 1,000 mg c/m2/day. what is the gross primary productivity for this community?

The general formula for calculating the net value is this

net = gross - deductions

The deduction is the respiratory rate

The net primary productivity is given

Solving for the gross primary productivity

gross = 2000 + 1000

gross = 3000 mg c/m2/day
