Which immediate ecosystem shift occurs when methane clathrates destabilize along a subduction zone?

💡 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.
