Revise: Metabolism and adverse conditions Daily torpor
Some animals can survive extreme conditions that are beyond the limits of their normal metabolic activity. Adaptations to achieve this include dormancy and migration.
Daily torpor is a period of reduced activity. This can be used to reduce the metabolic rate of an animals with highmetabolic rates. It only lasts a few hours and can be seen as a short-term hibernation.
Hummingbirds use daily torpor during the night to reduce their metabolic rate, which saves energy.
