Which effect results when tundra thaws and bioturbation increases?

💡 Explanation

Increased bioturbation mixes thawed organic matter with oxygen; this accelerates microbial decomposition via oxidation because enzymes are more active at warmer temperatures. Therefore, permafrost carbon oxidizes at faster rates, rather than reduced rates, under drier freezing conditions.
