What is the purpose of bees nests?

Bees build nests to protect themselves and their young. Nests can be made of various materials, such as wax, leaves, twigs, or even other bees' nests. The purpose of bee nests is to provide a safe and sheltered place for bees to lay their eggs, raise their young, and protect them from predators. Nests also serve as a source of food and water for the bees and their young.
