What is a common characteristic of insectivores like moles?

Insectivores, such as moles, are characterized by their diet, which predominantly consists of insects and their larvae. This diet is essential for their survival, as these creatures have evolved to efficiently hunt and consume these small, soft-bodied invertebrates. Moles, for instance, spend a significant amount of their time underground, tunneling through soil where they can find a variety of insects, earthworms, and other invertebrates that thrive in that environment.

The feeding habits of insectivores not only provide them with the necessary nutrients but also play a vital role in the ecosystem by controlling insect populations and contributing to soil aeration through their tunneling behavior. This specialization in their diet is a key factor that distinguishes insectivores from other types of mammals that may have broader dietary preferences, such as those that consume seeds, fruits, or rely on other mammals for sustenance. Therefore, option C accurately reflects the common characteristic shared by moles and other insectivorous animals.
