← Nature & AnimalsWhich outcome during intense rainfall can interrupt nitrogen fixation in soil?
A)Increased denitrification rate via bacterial respiration✓
B)Enhanced symbiotic plant-fungus nitrogen transfer
C)Improved soil aeration and plant growth
D)Reduced competitive inhibition of ammonia oxidizers
💡 Explanation
Increased denitrification occurs because anaerobic conditions increase due to waterlogging, which accelerates the rate of bacterial respiration that uses nitrate rather than oxygen; therefore less nitrogen is converted to ammonium rather than helping plant growth.
