What term describes animals whose body temperature remains constant regardless of external temperatures?

• A. Cold-blooded
• B. Ectothermic
• C. Warm-blooded
• D. Endothermic

Answer: (C)

The term that describes animals whose body temperature remains constant regardless of external temperatures is "warm-blooded," which refers to those animals that can maintain a stable internal body temperature through various physiological mechanisms. Warm-blooded animals, or endotherms, include mammals and birds, which have adaptations such as insulation (like fur or feathers) and metabolic processes that generate heat to keep their body temperatures within a narrow, optimal range regardless of environmental conditions. This ability allows them to be active in a wider range of temperatures and occupy various ecological niches. In contrast, other terms represent different thermoregulation strategies. Cold-blooded animals, also known as ectothermic, rely on external environmental temperatures to regulate their body heat, leading to fluctuating internal temperatures. Therefore, the distinction between warm-blooded and cold-blooded illustrates a fundamental difference in how these groups of animals interact with their environments.
