Quizplus · Accepted Answer

Butterflies are ectotherms, meaning they rely on external sources of heat to regulate their body temperature. Sunning themselves on a warm surface is a common behavior for ectothermic animals, as it allows them to increase their body temperature and promote metabolic activity. Endotherms, on the other hand, can generate heat internally through metabolic processes and maintain a relatively stable body temperature regardless of external conditions. Nonshivering thermogenesis is a process found in some endothermic animals, such as birds and mammals, where they can increase metabolic activity in their brown adipose tissue to generate heat. Acclimatization refers to the process of adjusting to environmental changes over time, and is relevant to both endothermic and ectothermic animals. Homeostasis refers to the process of maintaining a relatively constant internal environment, and is also relevant to both endothermic and ectothermic animals.
