The workers collect pollen and nectar from flowers. The pollen is used as a protein source and the nectar is an energy source. Some of the pollen lands on the pistils of the flower and results in cross-pollination. This is important for some crops and flowers. The relationship between the plant and the insect is called symbiosis.
Bees turn the nectar into honey.
Workers must visit over four thousand flowers to make just a tablespoon of honey. Beekeepers must be very careful when they remove honey from the hive. They try not to hurt the bees. The beekeepers give sugar syrup to the bees to replace the honey that they take. In 1957, it was accidentally released in Brazil during a science experiment.
