Which of the following is a main role of worker bees?

Worker bees play a critical role within the hive, and one of their primary functions is to collect nectar and pollen. This task is essential for the overall health and sustenance of the colony. Nectar is the primary source of carbohydrates for the bees and is ultimately converted into honey, which serves as their food supply, particularly during winter or when foraging is not possible. Pollen, on the other hand, provides protein and other nutrients necessary for the growth and development of the brood (young bees).

While other roles in the hive, such as defending the hive, building the hive structure, and laying eggs, are also important, these tasks are divided among different castes of bees. The queen bee is responsible for laying eggs, while drones do not participate in these activities. Worker bees, on the other hand, are the ones actively engaging in foraging, foraging, attending to the queen, caring for the brood, and managing the hive environment, showcasing their importance as the primary labor force within the colony.
