← GeographyWhich outcome from construction lowers ecosystem carbon sequestration?
A)Reduced soil bioturbation lowers carbon sinks✓
B)Enhanced surface runoff decreases nutrient supply
C)Increased albedo decreases radiative forcing
D)Disrupted hydrologic cycle enhances plant respiration
💡 Explanation
Reduced soil bioturbation via habitat destruction decreases soil respiration of organic matter, thereby weakening established carbon sinks, because burrowing organisms like earthworms increase soil aeration and nutrient turnover; therefore the reduced carbon sinking, rather than enhanced carbon uptake.
