Question

Global estimates of denitrification in terrestrial ecosystems vary widely but are of the order 200*102 g/yr, and more than half of that total occurs in wetland ecosystems. If restoration results in an increase in wetland area by approximately 25%, it would be expected that losses of nitrogen through denitrification would be closer to: A.175*1012 g/yr, 225*1012 g/yr, 275*1012 g/yr, 325*1012 g/yr?
