What effect does the presence of a strong queen have on a bee colony?

The presence of a strong queen significantly boosts a bee colony's morale and productivity. A healthy, well-mated queen is essential for the overall harmony and efficiency of the hive. Her ability to lay a considerable number of eggs ensures that the population of worker bees can be maintained or increased, directly influencing the colony's strength and capability.

Additionally, a strong queen releases pheromones that help establish and maintain the social structure of the hive. These pheromones serve as chemical signals that reinforce the roles of the worker bees, promote colony cohesion, and stimulate foraging behavior. As a result, the workers are more motivated and focused on their tasks, from foraging for food to caring for larvae, which ultimately enhances the productivity of the colony.

The other options do not align with the key roles a strong queen plays in a colony's dynamics. For instance, the egg-laying rate is positively influenced by a strong queen rather than decreased, and aggressive behavior is not a standard response to a strong queen. Similarly, nectar production is primarily a result of foraging activity, which is enhanced by a strong queen’s influence but is not a direct effect caused by her presence. Thus, the correct choice reflects the overall positive impact a robust queen has on the
