Clarify Question


• What is the key concept addressed by the question?
     o The question asks about differences between endotherms and ectotherms.

• What do you know about differences between endotherms and ectotherms? What other information is related to the question?
     o Ectotherms depend on external heat sources to warm their bodies, whereas endotherms use their own metabolically generated heat to warm themselves..


Choose Answer


• Given what you now know, what information is most likely to produce the correct answer?
     o A mouse is an endotherm and regulates its own body temperature through a high metabolism. A lizard is an ectotherm that absorbs heat from its environment and does not require as high a metabolism to maintain its body temperature. A mouse and a lizard of the same size will thus have different metabolic rates with the mouse being higher than the lizard.


Reflect on Process


• Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
     o This question asked you to apply your knowledge about differences between endotherms and ectotherms. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you realize that the mouse was an endotherm and the lizard an ectotherm? Did you think that an endotherm and ectotherm had the same metabolic rate?
