To compare: The costs and benefits of ectotherm and explain the strategies used by ectotherms to adjust their body temperature. Introduction: In order to survive and function properly animals need to maintain pH and internal temperature within relatively narrow limits. The state of the balanced internal environment is known as homeostasis. The body temperature is maintained within these narrow limits despite the changes in surrounding temperature through a process called thermoregulation. Ectotherms are those animals, which depend on the environment for their body heat, and it keeps changing with the change of temperature in the surroundings

Describe what happens in an endotherm and an ectotherm when outside temperature gets cold, and what happens when it gets hot.

Research the behaviours of a specific ectothermic animal. How do specific behaviours allow for the animal to control its body temperature in cool and hot conditions? How do specific parts of the animal’s anatomy help with thermoregulation? Use a feedback diagram to show how this animal uses thermoregulation in one of these conditions: ectotherm in cool conditions ectotherm in hot conditions Be sure to use ⊕ and ⊝ symbols in the feedback diagram to add important details.

From the list of strategies for dealing with harsh cold environments, choose those that an ectotherm would employ. See image attatched.
