Bee

Almost three million flowers are needed to make a kilo of honey.
In a single reconnaissance flight, a bee is able to visit between 50 and 100 flowers. For just one kilo of honey, it has been estimated that a single bee should fly about 150,000 kilometers, almost four times around the Earth, and that almost 60,000 round-trip flights are required from the hive to the flowers. Furthermore, 2,737,500 flowers would be needed to produce a kilo of honey.
