Which consequence results when prolonged anoxia occurs in flooded paddy fields?

💡 Explanation

Flooded soils become anaerobic, which favors methane production via methanogenesis because methanogens thrive in oxygen-deprived environment. Therefore methane production increases, rather than nitrogen fixation increasing due to lack of oxygen inhibiting nitrogenase activity.
