放热的

Ectothermic animals, such as reptiles and amphibians, rely on external sources of heat to regulate their body temperature.
外温动物，如爬行动物和两栖动物，依赖外部热源来调节体温。
In cold climates, ectothermic animals may hibernate or enter a state of torpor to conserve energy.
在寒冷气候中，外温动物可能会冬眠或进入蛰伏状态以节省能量。
The body temperature of an ectothermic animal fluctuates with the temperature of its environment.
外温动物的体温会随着环境温度的变化而波动。
Ectothermic animals are often more active in warm weather, as they require external heat sources to function optimally.
在温暖的天气里，外温动物往往更加活跃，因为它们需要外部热源才能最佳地发挥作用。
The metabolic rate of ectothermic animals is directly influenced by environmental temperatures.
外温动物的新陈代谢率直接受环境温度的影响。
Unlike endothermic animals, ectothermic animals do not have the ability to internally regulate their body temperature.
与恒温动物不同，外温动物没有能力内部调节体温。
Many ectothermic animals are ectothermic because they lack the specialized organs needed for endothermy.
许多外温动物是外温的，因为它们缺乏进行内温所需的特殊器官。
Ectothermic animals are particularly vulnerable to changes in their environment, such as habitat destruction or global warming.
外温动物特别容易受到环境变化的影响，比如栖息地破坏或全球变暖。
In some cases, ectothermic animals may bask in the sun to absorb warmth and raise their body temperature.
在某些情况下，外温动物可能会晒太阳以吸收热量并提高体温。
The behavior of ectothermic animals can be used to predict changes in the environment, as they are highly sensitive to temperature fluctuations.
外温动物的行为可以用来预测环境变化，因为它们对温度波动非常敏感。
