← GeographyWhich outcome accelerates after plant root death spurs invertebrate activity?
A)Increased carbon sequestration
B)Organic matter decomposition✓
C)Glacial ice accumulation
D)Atmospheric methane upwelling
💡 Explanation
Increased invertebrate activity causes faster organic material decomposition by bioturbation, because they redistribute and aerate soil to augment microbial access; therefore decomposition rate increases, rather than glacial ice accumulation without freeze-thaw cycles.
