How do ants protect their colonies?

Ants protect their colonies through teamwork, defensive behaviours, and specialised roles. Soldier ants guard the nest and fend off predators using powerful mandibles or stingers. Worker ants fortify the colony by repairing tunnels and closing entrances during threats. Ants also release alarm pheromones to alert the colony and coordinate a defensive response. These strategies ensure the survival of the colony.
