Which alteration occurs when Antarctic soil bioturbation declines?

💡 Explanation

Reduced bioturbation diminishes the **mixing of organic matter** back into the upper soil layers, because less faunal activity prevents nutrient redistribution from decomposition; therefore, upper layer nutrient levels fall off, rather than accelerating or increasing methane production.
