What a wild animal lives in earth?

The correct answer is: mole.

A mole is a small mammal that lives in burrows underground. Moles are found in all parts of the world except Antarctica. They are typically brown or black in color and have long, narrow bodies with short legs and large claws. Moles are known for their ability to dig tunnels through the ground. They use their claws to loosen the soil and then push it away with their feet. Moles can dig tunnels up to 100 feet long.

Moles are solitary animals and typically live alone in their burrows. They are active during the day and night and feed on insects, worms, and other small animals. Moles are not considered to be a threat to humans, but they can sometimes damage crops and gardens.
