The term DORMANT STATE IN WINTER can be summarized as hibernation, which is a state of inactivity and metabolic depression in certain animals during the winter season. Hibernation is a natural process that helps animals conserve energy and survive the cold temperatures of winter. During hibernation, animals enter a deep sleep-like state and their body temperature and heart rate drop significantly. This allows them to conserve energy and survive the winter months without having to search for food or water.
