← GeographyWhich outcome occurs more slowly as agricultural topsoil undergoes drastic reduction in arthropod populations?
A)Increased mineral horizon soil profile
B)Organic matter decomposition accelerates rapidly
C)Nutrient cycling and soil oxygenation✓
D)Reduced overall bulk bedrock formation
💡 Explanation
Reduced arthropods slow nutrient cycling and oxygenation because bioturbation by organisms promotes mixing and aeration of soil. This slows nutrient availability and soil system health, therefore overall soil system nutrient cycling stalls rather than decomposes quickly or affects bedrock formation.
