Detailed explanation-1: -Endotherms have various ways of increasing metabolic heat production, or thermogenesis, in response to cold environments. One way to produce metabolic heat is through muscle contraction-for example, if you shiver uncontrollably when you’re very cold.

Detailed explanation-2: -Another adaptation to control body temperature that endotherms have is the ability to shiver. This involuntary movement of your muscles when you get cold Page 2 burns calories. Heat is released. Shivering helps keep your body warm.
