Answer:
Honey bees — wild and domestic — perform about 80 percent of all pollination worldwide. A single bee colony can pollinate 300 million flowers each day. Grains are primarily pollinated by the wind, but fruits, nuts and vegetables are pollinated by bees. Seventy out of the top 100 human food crops — which supply about 90 percent of the world’s nutrition — are pollinated by bees.

rhetorical question is one for which the questioner does not expect a direct answer: in many cases it may be intended to start a discourse, or as a means of displaying the speaker's or author's opinion on a topic
