You can remember the difference between endotherms and ectotherms if you remember that endo- means inside endo- = inside and ecto- means outside ecto- = outside, so endotherms generate their own heat from within, and ectotherms get their heat from the outside.
Homeostasis is the process of maintaining a consistent environment inside the body. For warm-blooded animals such as mammals and birds, homeostasis is a combination of internal processes involving hormones, the endocrine system and metabolism.Cold-blooded animals like snakes, on the other hand, have no such internal systems in place, and must rely on their external environment to maintain homeostasis.he Thermoregulation Process. Thermoregulation is the process of regulating body temperature, which is a major part of homeostasis. Snakes and other ectotherms are cold-blooded animals that lack the ability to generate body heat internally.
