Final answer:
Cold-blooded organisms, such as reptiles, amphibians, and most fish, rely on environmental heat to regulate their body temperature. In colder environments, they become less active or seek warmth. This behavior is due to their ectothermic nature; they cannot generate internal body heat.
Step-by-step explanation:
Examples of Cold-Blooded Organisms
Cold-blooded organisms, which are also referred to as ectothermic, depend on external environmental temperatures to regulate their body temperature. Examples of cold-blooded organisms include reptiles, such as snakes and lizards; amphibians, like frogs and salamanders; and most fish, which are covered with scales, have paired and unpaired fins, and a streamlined body that helps them swim rapidly.
Behavior of Cold-Blooded Organisms in the Cold
When it is cold outside, cold-blooded organisms may behave differently since their body temperature is directly influenced by their environment. These organisms tend to become less active, may hibernate, or seek out warm areas to maintain an adequate body temperature necessary for survival. The ectothermic nature of these animals means they cannot generate their own heat and must therefore rely on sun exposure or other heat sources to stay warm.
