Question
Chapter 33, Problem 3MCQ
Summary Introduction
Introduction:
The mechanism through which the body temperature is controlled is known as thermoregulation. The heat gained from the environment, and lost to the environment is balanced with the body in this process, and thermoregulation is responsible for maintaining the homeostasis of the body in the endotherms.

Students have asked these similar questions
Why to humans shiver when the environment gets cold?a. To keep the body temperature equal to the external environment.b. To increase body temperature.c. To decrease body temperature.d. To regulate urine concentration.
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.
Make a claim that answers the question: How does temperature affect endotherms and ectotherms differently?

- You are studying a large tropical reptile that has a high and relatively stable body temperature. How do you determine whether this animal is an endotherm or an ectotherm? (A) You know from its high and stable body temperature that it must be an endotherm. (B) You subject this reptile to various temperatures in the lab and find that its body temperature and metabolic rate change with the ambient temperature. You conclude that it is an ectotherm. (C) You note that its environment has a high and stable temperature. Because its body temperature matches the environmental temperature, you conclude that it is an ectotherm. (D) You measure the metabolic rate of the reptile, and because it is higher than that of a related species that lives in temperate forests, you conclude that this reptile is an endotherm and its relative is an ectotherm.arrow_forwardWhich of the following is not a way that ectotherms can change their body temperatures? a.
