Which 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.
