Bees are small insects, but they do a very big job. When a bee visits a flower to drink its sweet nectar, yellow dust called pollen sticks to its body. Then the bee flies to the next flower and carries the pollen with it. This helps the plants make fruit and seeds.
Without bees, we would have fewer apples, almonds, watermelons and many other foods.
Honeybees live together in a hive. In one hive there can be 50,000 bees, but only one queen. The queen lays eggs, and the worker bees collect food, clean the hive and take care of the babies.
Today there are fewer bees in the world than in the past. Scientists say that poisons in gardens and fields are one reason. You can help by planting flowers on your balcony.
