Here's why:
* Ectothermic animals rely on external sources of heat to regulate their body temperature. Think of reptiles like lizards who bask in the sun to warm up.
* Endothermic animals, like rabbits, generate their own body heat through metabolic processes. This allows them to maintain a stable internal temperature even in changing external environments.
Therefore, rabbits are warm-blooded and maintain a relatively constant internal temperature regardless of the external temperature.
