D) the rate of decomposition by detritivores
E) the annual total of incoming solar radiation per unit of area

Question

Quizplus · Accepted Answer

Net ecosystem production (NEP) is typically estimated by measuring the net flux of CO₂ or O₂ in or out of an ecosystem. This can be done using various techniques such as eddy covariance, chamber measurements, or remote sensing. By measuring the difference between the amount of CO₂ released by respiration and the amount of CO₂ taken up by photosynthesis, NEP can be calculated to determine whether an ecosystem is a net sink or source of carbon.
