To determine: The strategies used by ectotherms to adjust their body temperature.
Introduction: Animals need to maintain a balanced state of body temperature to survive and function properly. The body temperature is maintained within narrow limits despite the changes in the surrounding temperature through a process called thermoregulation.

- What is the trade-off of ectotherms with regard to maintaining an internal environment that doesn’t vary much? Ectotherms are larger than endotherms because they need to have a larger surface area to volume ratio in order to either increase or lower their temperature. Ectotherms usually have fur in order to conserve heat when they live in very cold environments. Ectotherms are smaller than endotherms because they need more surface area to dissipate heat relative to their insides. Ectotherms can survive in a wider variety of habitats because they are smaller and can behaviorally adapt to a wide variety of temperatures.arrow_forwardWhich of the following is not a way that ectotherms can change their body temperatures? a. Sweating for evaporative cooling. b. Adjusting the timing of their daily activities. c. Seek out or avoid direct sunlight. d. Huddle in a group.arrow_forwardMany marine fish swim into deep, cold water to pursue prey or avoid predators. How does cold temperature influence their ability to swim? What other affects will the cold water have on their body?arrow_forward
- The main difference between ectotherms and endotherms is how they obtain food to provide for their metabolism. the source of their body heat. whether they conserve or eliminate body heat. whether they control their body temperature.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_forwardResearch 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_forward

- How do other body systems work to restore homeostasis when the kidneys are not working correctly?arrow_forwardWhich of the following statements best summarizes the difference between ectothermic and endothermic organisms? Group of answer choices Ectotherms absorb external heat, but endotherms use metabolic heat to maintain a warm, steady body temperature Ectotherms are warm-blooded, but endotherms are cold-blooded Endotherms control their temperature, but ectotherms have no control over their temperature Endotherms are warm-blooded, but ectotherms are cold-bloodedarrow_forwardWhat is the difference between anatomy and physiology?How do these two sciences support each other?arrow_forward
