← ScienceWhich outcome occurs when dissolved molecular oxygen concentration depletes within a marine sediment layer?
A)Anaerobic respiration rate increases✓
B)Ammonia oxidation accelerates rapidly
C)Nitrification processes dominate thoroughly
D)Phosphate precipitation reactions accelerate
💡 Explanation
Anaerobic respiration increases because the *electron acceptor availability* shifts from oxygen to substances like nitrates; therefore, anaerobic pathways become dominant, rather than the aerobic oxidation processes which are inhibited by hypoxia.
