Cold-blooded organisms

• Body temperature is (mostly) the same as the environment

Pros and cons:

• No energy needed to keep body temperature up
• Cold > not much respiration > not much energy
• Hibernation > Hibernate to survive cold times

Pros and cons

• A lot of energy is needed to keep body temperature up
• Cold > More respiration is needed
• Cold climates > thick fur/layer of fat = insulation
