Which castes of termites are typically responsible for foraging for food?

Workers are the castes of termites that are typically responsible for foraging for food. This designation stems from their essential role in the colony, where they handle various tasks, including foraging, nest construction, caring for the brood, and maintaining the structure of the colony. Their anatomical adaptations, such as smaller size and lack of wings compared to other castes, enable them to navigate well within the habitat while searching for food sources.

The soldier caste is primarily focused on defense, protecting the colony from predators. Reproductive termites, which include the queen and king, are responsible for the reproduction and expansion of the colony, leaving foraging duties to the worker caste. Therefore, it's clear that the workers play a vital and singular role in food acquisition, making them the correct answer to the question regarding which castes are typically responsible for foraging.
