Can you explain the differences between an ectotherm and an endotherm in animals?

Understanding the Differences Between Ectotherm and Endotherm in Animals

When it comes to the thermoregulation of animals, two main categories are commonly referred to: ectotherms and endotherms.

Focus Keyword: Ectotherm vs. Endotherm

Ectotherm:

An ectotherm is an organism that relies on external sources to regulate its body temperature. These animals do not internally produce enough metabolic heat to maintain a stable internal temperature.

Endotherm:

In contrast, endotherms are animals that can regulate their body temperature through internal means. They have the ability to produce metabolic heat to keep their internal environment constant, regardless of external temperatures.

Overall, the key difference between ectotherms and endotherms lies in how they manage their body temperature - one depends on external factors, while the other generates heat internally.
