The ectotherm from the given options is the Rattlesnake.
To determine which of these animals would be considered an ectotherm, we need to understand what an ectotherm is. An ectotherm is an animal that relies on external sources of heat to regulate its body temperature. They cannot generate their own body heat internally.
Now, let's consider each animal from the given options:
1. Lion: Lions are endotherms, also known as warm-blooded animals. They are capable of producing their own body heat, so they are not ectotherms.
2. Red Tailed Hawk: Similar to lions, hawks are also endotherms. They generate their own body heat, making them warm-blooded animals, not ectotherms.
3. Rattlesnake: Rattlesnakes are ectotherms. They rely on external sources of heat, such as basking in the sun, to regulate their body temperature. This makes them cold-blooded animals and an example of an ectotherm.
4. Polar Bear: Polar bears are endotherms. They are capable of generating their own body heat to maintain their body temperature, so they are not ectotherms.
Therefore, the animal considered an ectotherm out of the given options is the rattlesnake.
