Black bears are remarkably adaptable animals and can survive for extended periods without food or water. In the wild, black bears have been known to hibernate for up to 7 months without eating, drinking, urinating, or defecating. During this time, they rely on stored body fat as a source of energy and sustenance. As for water, while hibernating, black bears do not drink water, and instead, they metabolize body fat to meet their water requirements. This ability to survive extended periods without food or water is a remarkable adaptation that allows black bears to endure harsh conditions and scarcity of resources in their natural habitats.
