How do fire ants build their colonies?

Fire ants build their colonies by excavating soil and creating a network of tunnels and chambers. These structures provide shelter for the queen, workers, and brood, as well as storage for food. The colony is organised into different zones for specific activities, such as raising larvae or defending the nest. Fire ants communicate through pheromones, coordinating their efforts to expand the colony and defend against threats. Their ability to work collectively and adapt to changing environments has contributed to their success as a species.
