Hibernation: Nature's Winter Survival Strategy

The video explores how animals rely on food for energy and adapt to food scarcity in winter through migration or hibernation. Hibernation is an adaptation that helps conserve energy and offers protection from predators. It occurs in over 200 species, including mammals, amphibians, and invertebrates. Some animals also estivate during hot summers. Preparation for hibernation involves storing fat, with processes like hyperphagia in bears. The video concludes with a review and quiz on hibernation concepts.
