← GeographyWhich outcome results when soil organisms experience temperature extremes?
A)Increased anaerobic respiration of microbes
B)Decreased nutrient translocation efficiency
C)Inhibited bioturbation mixing activity✓
D)Enhanced mineral ion cation exchange
💡 Explanation
Inhibited bioturbation occurs because extreme soil temperatures damage or kill soil organisms, therefore reducing their mixing action, rather than boosting respiration; extreme temperatures do not directly impact cation exchange, because it's a chemical process unaffected by biotic stress.
