What is a key characteristic of worker termites?

Worker termites are characterized by their significant role within the colony, which is why they are the most numerous caste. They are responsible for foraging for food, caring for the queen's eggs, and maintaining the nest. This large population allows the colony to function effectively, as workers carry out essential tasks that support the survival and growth of the colony.

In contrast, while some termites do possess wings during certain life stages, workers do not have wings in their adult form. Additionally, workers do not reproduce; that role falls to the queen and king of the colony. Lastly, worker termites are not the largest in size; typically, the queen is the largest member of the colony, responsible for reproduction. Therefore, the prominence of worker termites in numbers directly correlates with their fundamental duties in sustaining the colony, establishing this characteristic as key.
