← GeographyWhich outcome results when limited oxygen inhibits bioturbation?
A)Anaerobic sediment layer consolidation forms✓
B)Plant nutrient cycling becomes accelerated
C)Decreased methane outgassing from permafrost
D)Oxidation rates increase in peat bogs
💡 Explanation
Anaerobic consolidation appears because oxygen starvation reduces bioturbation; earthworms and arthropods promote aerobic processes, increasing decomposition rates, thereby allowing sediment settling, rather than faster nutrient cycling, a different outgassing profile or increased oxidation.
