How Do Ants Live?
Ants live underground or in wood. Their homes are called nests. Inside the nest, ants work together. They build tunnels and rooms. Ants work hard to keep the colony safe. They find food and bring it back to the nest.

Ants use their strong jaws to bite. These jaws are called mandibles. Mandibles help ants cut, carry, and fight. When ants bite, they clamp their mandibles on the skin. Some ants can also sting and inject venom. This venom can cause pain and swelling.
