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.

Desert lizardarrow_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_forward
- 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.arrow_forwardIn terms of body temperature regulation, contrast “cold-blooded” (Ectothermic or poikilothermic) and “warm-blooded” (Endothermic or homeothermic).
