Question
Chapter 40, Problem 7TYU
Summary Introduction
To explain: Which animal uses the largest fraction of its energy budget for homeostasis.
Introduction:
Homeostatic regulation is a process performed by an animal to maintain its internal environment. An animal maintains a steady state, a relatively constant internal environment, even when the external environment changes significantly.

Students have asked these similar questions
An animal’s inputs of energy and materials would exceedits outputs(A) if the animal is an endotherm, which must always take inmore energy because of its high metabolic rate.(B) if it is actively foraging for food.(C) if it is growing and increasing its mass.(D) never; due to homeostasis, these energy and materialbudgets always balance
An ectotherm (a) has a higher rate of enzyme activity than a typical endotherm (b) has a variety of homeostatic mechanisms or regulating body temperature (c) depends on sensors in the hypothalamus to regulate temperature (d) may use behavioral strategies to help adjust body temperature (e) must expend more energy on thermoregulation than an endotherm
What occurs as body size increases in animals ?
there is a decrease in the surface-to-volume ratio.
reproduction becomes limited to terrestrial environments.
there is greater variability in metabolic rate.
migration to tropical areas becomes necessary for thermoregulation.
it becomes more difficult to conserve body warmth in cold environments.

- 1) It is _____for aquatic vertebrates to maintain a body temperature different from their surroundings because ______. A) easier; water is a much better insulator than air due to its greater density B) easier; it is possible for fish to absorb heat from the surrounding water by countercurrent exchange even when the water is colder than the fish C) harder; water is a better conductor of heat than air D) harder; terestrial vertebrates can use countercurrent exchange to absorb heat from air that is cooler than their bodies 2) Compared to terrestrial environments, marine environments have_____." A) greater differences in temperature between hot and cold seasons B) smaller differences in temperature between hot and cold seasons C) the same amount of seasonal variability in temperaturearrow_forwardElephant seals do deep dives to forage for food. The energy used by the seals in diving depends on their body composition; for example, fatter seals use less energy to swim to the surface at the end of a dive, allowing them to takelonger, more productive dives. Explain why you’d expect this to be the case.arrow_forwardConsider an ectotherm and an endotherm of equal body mass. Which of the following would you expect to be true? -both animals require the same amount of energy per unit mass -the ectotherm requires more daily calories from food than the endotherm -the endotherm requires less energy per unit mass but more total energy than the ectotherm -the ectotherm requires less energy per unit mass but more total energy than the endotherm -the ectotherm could survive a longer period without food relative to the endothermarrow_forward
- As body size increases in animals, there is greater variability in metabolic rate. it becomes more difficult to conserve body warmth in cold environments. migration to tropical areas becomes necessary for thermoregulation. there is a decrease in the surface-to-volume ratio. reproduction becomes limited to terrestrial environments.arrow_forwardYou 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_forwardImagine if mermaids are real. What are their biological and Physical demands (LOCOMOTION, BREATHING, and THERMOREGULATION)?arrow_forward
- Consider the following energy demands: basal metabolism, reproduction, thermoregulation, activity, and growth; How should the energy spent toward these demands differ between an endotherm and an ectotherm of the same size?arrow_forwardWhat adaptations help your animal(lion) gather or eat food?arrow_forwardWhen you exercise, your body depletes oxygen faster. As a result, respiration and depth of breathing increases to take in more oxygen. In addition, your heart rate increases to speed up the delivery of oxygen to your muscles that are exercising. What type of homeostatic mechanism does this represent? a) Positive feedbackb) Negative feedbackc) Feedforwardarrow_forward
