- The definition of endothermic is a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature.
- A chemical reaction that works only if heat is absorbed is an example of a reaction that would be described as endothermic.
- A warm-blodded animal would be an example of an endothermic animal.
Warm-blooded animals, like this rabbit, are endothermic animals.
