Answer:
Homeostatsis
Step-by-step explanation:
Mammals are homoeothermic, which means they can adjust their body temperature as per change in temperature of the surroundings. This is called homeostasis.
Homeostasis is a self-regulatory process by which some organisms such as mammals, birds maintains their internal environment constant.
For examples, the body of a human body functions optimum at normal temperature which is 37°C. If the body temperature increases well above 37°C, then by self-regulatory process body bring down temperature to the normal.
