"The worker bee has a mass of 125 mg. It is one of the main flower pollinating insects. The bee has two special baskets, one on each of its back pair of legs, which it uses to carry
pollen. As it moves from flower to flower to drink nectar, it also collects pollen which it stores in its pollen baskets. Each pollen
basket has a mass of 7,5 mg when full. During 10 hours of a summer's
day, one bee can carry 750 mg of pollen into the hive.
One of the bee's favourite flowers is clover. Each clover flower provides
0,03 mg of pollen which the bee adds to its pollen baskets."
