What is the primary role of worker ants in their colony?

The primary role of worker ants in their colony is foraging for food. Worker ants are responsible for gathering food to sustain the colony, which includes scavenging, hunting, and transporting food back to the nest. This task is crucial for the survival of the colony, especially during periods when food sources may become scarce.

In addition to foraging, worker ants also engage in various other activities such as tending to the queen and brood, maintaining and defending the nest, and participating in the overall organization of the colony. However, their main function is to ensure that the colony has enough food to thrive, which makes foraging the centerpiece of their responsibilities.
