Bees can see colors we cannot see, and they can detect minute amounts of chemicals we cannot sense. unlike many insects, bees cannot hear very well. a biologist would probably give which of the following as the ultimate explanation for their poor hearing?

Had to look for the options and here is my answer.
Based on the ability of the bees to hear, their sense of hearing is weak and the one that best explains their poor hearing is that "hearing may not contribute much to a bee's reproductive success". This is based on the actual options posted with this question.
