← GeographyWhich immediate ecosystem shift occurs when methane clathrates destabilize along a subduction zone?
A)Anaerobic microbial oxidation increase✓
B)Habitat complexity greatly increases
C)Photosynthetic production surges
D)Ocean acidification risk decreases
💡 Explanation
Increased methane release fuels anaerobic oxidation by microbes because a pressure drop allows clathrates to dissociate near subduction zones, therefore anaerobic conditions expand rather than support complex oxygenated habitats.
