Summary
Reduced metabolism and body temperature allow animals to survive scarce winter food.
In depth
Body temperature and metabolic rate drop sharply; hibernating bears reduce heart rate but remain relatively warm, while ground squirrels cool near 0 °C. Brown fat and stored fat provide energy. Daily torpor occurs in hummingbirds and bats.
Torpor reduces energy needs. Arousal costs energy. Hibernators may be periodically aroused.
Remember: bears are light hibernators with moderate temperature drop.

How is Hibernation and Torpor different from Thermoregulation in Animals?
Hibernation and Torpor: Reduced metabolism and body temperature allow animals to survive scarce winter food. Thermoregulation in Animals: Endotherms generate heat internally while ectotherms rely on external heat sources. Read both side by side and note what each one explains.
