One third of the world's food supply requires insect pollination, and 80% of those crops are pollinated by bees. Pollination occurs as bees visit flowers for nourishment, eating nectar for energy and pollen for protein. Pollen sticks to the bees' leg hairs and is brushed off as the bees move from flower to flower, fertilizing the plants.
