Detailed explanation-1: -Shivering helps keep your body warm. This is an example of a metabolic way that endotherms can regulate their body temperature. However, this ability comes at a cost. Since energy must be used to maintain the animal’s body temperature, more energy is required for the animal to live.

Detailed explanation-2: -A very simple method endotherms use is shivering. Shivering is a response to cold environmental temperatures. When endotherms shiver, they are rapidly contracting their muscles, which expends energy.

Detailed explanation-3: -Endotherms generate most of the heat they need internally. When it’s cold out, they increase metabolic heat production to keep their body temperature constant. Because of this, the internal body temperature of an endotherm is more or less independent of the temperature of the environment.

Detailed explanation-4: -Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Endotherms can alter metabolic heat production to maintain body temperature using both shivering and non-shivering thermogenesis.

Detailed explanation-5: -In order for an ectotherm to warm up it would bask in the sun, or if it needed to cool down it could burrow or seek shade. These are physical interactions with the environment since the ectothermic organism can not rely on physiological processes like the endotherm (such as sweating and shivering).
