問題詳情

請依下文回答第 8 題至第 12 題         When a bee returns from a more distant food source, she does what is called the Schwanzeltanz or the waggledance. She wags her abdomen as she runs straight a short distance while making a rasping sound with her wings.She makes turns that create a figure-eight design. The movements of the dance indicate to the other bees in thehive where they must fly to find the food. Karl von Frisch was the first to decode the dances of the honeybees. Asearly as the 1940s, he found that honeybees can communicate the direction, distance, and quality of a food sourceto members of their hive through elaborate dances. Scientists have also discovered that the bees produce ahive-specific pheromone that they leave at the source of the nectar, helping to direct the other bees to the site. Apheromone is a chemical that is secreted by one individual and acts from a distance on another individual to alterthat individual’s behavior. The scout bee also brings back the scent of the nectar itself, which further aids theother bees in locating the food source. So there are several indicators of where the food is located: the “dance,” thepheromone, and the odor of the food.
