How is Net Ecosystem Production (NEP)typically Estimated in Ecosystems

Question

How is net ecosystem production (NEP)typically estimated in ecosystems?
A)the ratio of producers to consumers
B)the amount of heat energy released by the ecosystem
C)the net flux of CO₂ or O₂ in or out of an ecosystem
D)the rate of decomposition by detrivores
E)the annual total of incoming solar radiation per unit of area

Accepted Answer

Net ecosystem production (NEP) is typically estimated by measuring the net flux of CO₂ or O₂ in or out of an ecosystem, as this reflects the balance between photosynthesis and respiration. This can be measured using techniques such as eddy covariance or chamber-based methods.
