Some ant colonies consist of a queen, who performs all reproductive duties for the colony, and worker ants, who perform all the labor that the colony needs to gather food, expand and defend territory, and survive. The worker ants are also able to—but do not—contribute reproductively to the colony. In a colony like this, the worker ants will give their lives to defend the queen. Why is the worker ant considered altruistic?

The worker ant is considered altruistic as they forgo reproduction for the clan.

Altruistic behavior demonstrates the act where one person willingly sacrifices their own benefits for another individual. It shows the social responsibility as well as volunteering behavior in the family or society.

Therefore, worker ants make self-sacrifice of reproduction and fight for their kin to protect them from other clans.
