WebBoth amphibians and reptiles are ectotherms, meaning that they derive heat from the environment, rather than producing it internally. To say that they are cold-blooded is imprecise since they, like endothermic vertebrates, need to keep warm in order to remain active. Ectotherms are forced to slow down as their environment cools. WebScience Earth Science Q3.14. Some migratory birds are heterothermic, meaning they sometimes maintain a constant body temperature and other times allow their body temperature to vary. For example, on cold nights, they sometimes reduce their metabolic rate and allow their body temperature to drop as the air temperature falls.

WebEctotherms, on the other hand, are animals that don't use metabolic heat production to maintain a constant body temperature. Instead, their body temperature changes with the temperature of the environment. Lizards … WebMay 27, 2024 · Ectotherms have developed several behavioral thermoregulation mechanisms, such as basking in the sun to increase body temperature or seeking shade to decrease body temperature.
