Which outcome occurs when burrowing organisms introduce significant bioturbation in permafrost regions?

💡 Explanation

Thawing permafrost releases trapped organic material. Increased bioturbation mixes the thawing soil, accelerating organic material decomposition and subsequent microbial action, a process called methanogenesis. This causes accelerated methane venting because anaerobic decomposition increases CH4 production rather than restricting wildfires; therefore venting occurs.
