What do voles typically eat?

Voles primarily feed on a diet that consists of the roots and stems of grasses, seeds, and bulbs. This preference for herbaceous material reflects their role in the ecosystem as herbivores. Their feeding behavior can cause significant damage to lawns and gardens, particularly in cool-season turfgrass areas where they are often found. This diet not only sustains them but also plays a role in the management of plant populations in their habitats.

While other options mention various types of food, they do not accurately reflect the primary diet of voles. For instance, while some animals may consume soft fruits and vegetables or even insects, that is not typical for voles. Additionally, their limited consumption of animal matter distinguishes them from other small mammals that might have a broader diet. The focus on grasses, seeds, and bulbs is a defining characteristic of what voles eat, confirming choice B as the accurate response.
