What role do soldier termites play in a colony?

Soldier termites play a critical role in the defense of the colony against various predators, including ants and vertebrates that threaten their survival. They are characterized by their large mandibles, which they use to protect the colony from invasions and attacks. By defending the colony, soldier termites ensure that the workers and the queen can focus on their tasks, such as foraging for food, caring for the young, and maintaining the nest. This protection is vital for the overall health and sustainability of the colony, allowing it to thrive in its environment.

The other roles mentioned in the options pertain more to worker termites, who are responsible for building tunnels, searching for food sources, and nurturing the young, showcasing the specialized functions within the termite social structure. Soldier termites specifically divert their energy and resources towards safeguarding the community, making their role distinct and essential for the colony's survival.
