Which term matches the definition: an animal that is able to control its body temperature from within?

Explanation:
Endotherms actively maintain their body temperature from within by generating heat through metabolism and using adaptations like insulation. This internal heat production lets them stay active across a wide range of environments and times. Germination and cotyledon are plant-related terms—germination is seed sprouting, and cotyledon is a seed leaf—so they don’t describe animal temperature control. Ectotherms, in contrast, rely on the environment for heat rather than producing it themselves. So the term that matches the definition is endotherm.
