Mammals Regulate Their Own Body Temperature
Yes, mammals are endothermic organisms. This means they can regulate their own body temperature internally, maintaining a stable core temperature even when the external environment changes.
How Mammals Stay Warm
- Metabolic processes: Mammals have a high metabolic rate, generating heat through cellular respiration.
- Insulation: Fur and blubber help trap heat and reduce heat loss.
- Physiological mechanisms: Shivering and sweating are examples of physiological responses that regulate temperature.
Therefore, mammals are able to thrive in a wide range of environments, unlike ectothermic animals such as reptiles, who rely on external sources of heat.
