Which term describes animals that maintain their own body temperature, independent of the environment?

Explanation:
Endothermy is the ability to keep a stable internal body temperature by generating heat metabolically and using insulation. Animals that are endothermic, like many mammals and birds, can stay warm in cold surroundings and cool down when it’s hot, largely independent of the environment. Reptiles are typically ectothermic, meaning their body temperature largely follows the temperature of their surroundings. Most fish are also ectothermic, with body temperature matching the water. Insectivore describes what an animal eats, not how it regulates temperature, so it’s not about thermoregulation.
