'Ectotermia'是希腊语，中文翻译为“外温动物”，是指无论环境温度如何，动物体内代谢产生的热量都无法维持其体温稳定，而需要从外部环境获取温度来维持生命活动的一类动物。
以下是含有“Ectotermia”这个词语的9个例句：
1. Ectotermia animals are ectothermic because they are unable to produce the internal heat necessary to maintain a constant body temperature.（外温动物是外温动物，因为它们无法产生维持恒定体温所必需的内部热量。）
2. Many reptiles are ectothermic and rely on external sources of heat such as sunlight to regulate their body temperature.（许多爬行动物是外温动物，依赖外部热源如阳光来调节体温。）
3. Ectothermic animals are usually more active in warmer temperatures as their internal temperature rises, which in turn increases their metabolism.（外温动物在温暖的温度下通常更活跃，因为它们的内部温度上升，进而增加了它们的新陈代谢。）
4. Ectothermic animals need to bask in the sun to increase their body temperature and become more active.（外温动物需要靠晒太阳来增加体温并变得更活跃。）
5. Unlike ectothermic animals, endothermic animals such as mammals and birds can maintain a constant body temperature by producing internal heat through their metabolism.（与外温动物不同，哺乳动物和鸟类等恒温动物可以通过代谢产生内部热量来维持恒定体温。）
6. Some marine organisms such as fish and sharks are ectothermic and their body temperature is largely determined by the surrounding water temperature.（一些海洋生物如鱼类和鲨鱼是外温动物，其体温大多由周围水温所决定。）
7. Understanding the physiology and behavior of ectothermic animals is important in fields such as ecology and conservation biology.（理解外温动物的生理和行为对于生态学和保护生物学等领域很重要。）
8. Ectothermic animals are more vulnerable to changes in their environment such as temperature fluctuations and habitat loss, making them more susceptible to extinction.（外温动物更容易受到环境变化如温度波动和栖息地丧失的影响，使它们更容易灭绝。）
9. The study of ectothermic animals has led to the development of technologies such as heat lamps and incubators that can be used to control the temperature and habitat of these animals in captivity.（对外温动物的研究导致了技术的发展，如加热灯和孵化器，可以用于控制这些动物在圈养环境中的温度和栖息地。）
