Is a llama ectotherm or endotherm?

Llamas are endotherms. This means they can regulate their own body temperature internally, rather than relying on external sources of heat like the sun.

Here's why:

* Fur: Llamas have thick, woolly coats that help insulate them and maintain their internal body temperature.

* Metabolic Rate: They have a higher metabolic rate than ectotherms, which allows them to generate their own heat.

* Behavior: Llamas can shiver to generate heat when cold, and they can pant and sweat to cool down when hot.

So, while llamas may bask in the sun to warm up, they are primarily endotherms and have the ability to keep their body temperature stable regardless of external temperatures.
