Summary Introduction
Introduction:
Thermoregulation is a mechanism by which the internal temperature of the body is maintained by exchanging heat with the surroundings. It occurs in ectothermal animals like fishes and amphibians. The endothermal animals have an internal mechanism for regulating and maintaining the temperature inside their body by the generation of energy in the
Therefore, the ectotherms and endotherms differ in the mechanism of the regulation of heat exchange inside the body due to the mechanism of thermoregulation.

Students have asked these similar questions
Which of the following statements is True?a. Ectotherms generate most of their body heatmetabolically.b. Ectotherms include birds and mammals.c. Ectotherms experience variable body temperatures.d. Ectotherms are known as “warm-blooded” animals.
Which of the following is a correct statement about endothermic organisms?
A. Compared to ectotherms, since they cannot have their internal body temperature leave the thermoneutral zone, they are limited with regard to the types of environments they can live in.
B. Endotherms do not typically use passive mechanisms for thermoregulation, such as insulation, because they utilize metabolic energy to control body temperature.
C. The trait of endothermicity is a derived characteristic in mammalian animals and is not seen in other phylogenetic branches in the Metazoan Clade.
D. All endotherms possess sweat glands, which allow them to conduct evaporative cooling to lower their body temperature when needed.
E. None of the above
Thermoregulation is the process by which animals maintain an internal temperature within a
tolerable range.

range of external temperatures
O d. Ectothermy is more energetically expensive than endothermy

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_forwardTopic: Temperature Regulation and Osmotic Balance Choose the letter of the correct answer in each question.
