- Their body temperature remains constant all the time
- They kill all the animals they come across
- Their blood remains cold all the time
Correct Option: B
A cold blooded animal, or ectotherm, is one that does not have an internal mechanism for regulating its body temperature. Instead, a cold blooded animal relies on solar energy captured by the environment. Reptiles, amphibians and fish are examples of cold blooded animals. To change their body temperature, cold-blooded animals move to different places in their habitat. They may burrow under the ground, crawl under a log or a rock, etc. Cold-blooded means that the animals are ectothermic. They are dependent on the environment to control their body temperature.
