Adaptation and diversity of living organisms

The video explains how animals adapt to winter through hibernation, migration, and fur changes. Hibernation involves fat storage for energy during long sleep periods. Migration is another strategy, with animals like caribou traveling to find food and shelter. Some animals, like deer and weasels, adapt by changing their fur to better insulate against the cold. These adaptations help animals survive harsh winter conditions.
