Are reptiles ectothermic or endothermic?

Answer 1

Ectothermic

Reptiles must modify their behavior in order to maintain a relatively stable internal temperature, despite changes in the ambient temperature, because they lack the physiological processes necessary to maintain a constant internal temperature. As a result, they bathe in the sun.

Since reptiles lack the ability to produce heat through metabolic reactions, which require energy, they must find other ways to maintain their body temperature, most often through behavioral changes. Endotherms, like humans, can generate heat through metabolic reactions.

Reptiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
