Which outcome occurs more slowly as agricultural topsoil undergoes drastic reduction in arthropod populations?

💡 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.
