Why do camels have humps?

Camels have humps to store fat, which provides them with energy during times when food and water are scarce. The fat in the hump can be metabolized into both energy and water, allowing camels to survive in arid desert environments. Contrary to popular belief, camels do not store water in their humps; instead, they rely on the fat to fuel their body when necessary. This adaptation helps them endure the extreme conditions of the desert, where food and water can be scarce for long periods.
