What role do moles play in the ecosystem despite creating mounds?

Moles play a beneficial role in the ecosystem despite their tendency to create mounds in landscapes and gardens. Their burrowing activities help aerate the soil, which improves water infiltration and root growth for plants. Through their foraging, moles also help control insect populations, particularly grubs and other soil-dwelling pests. This natural predation can lead to healthier turfgrass and gardens by reducing the numbers of harmful pests that could otherwise damage plant growth. Therefore, their presence contributes positively to soil management and pest control, making option B the correct choice.
