CHAPTER 16 NOTES 0.0 / 5 ? BiologyTemperature regulation and water balanceAll LevelsAll boards Created by: ALK756Created on: 18-10-15 09:19 What are ectotherms? What are some examples? Ectothermic animals are animal that have very little control their body temperature. Examples are reptiles and insects. 1 of 14 What are disadvantages of an ecotherm? They cannot produce internal heat and they lose heat to the environment quickly. 2 of 14 How do ectotherms control their body temperature? Ectotherms rely mainly on behavioural adaptations to help control their body temperature. 3 of 14 What is a heterotherm? Give an example Heterotherms are ectotherms that function as an endotherm. An example of this would be a fish. 4 of 14 What are endothems? Endotherms are animals that can maintain a relatively constant body temperature. 5 of 14 How do endotherms maintain a constant body temperature? They do this by generating metabolic heat and by having insulating structures. 6 of 14 What does the hypothalamus do? Controls body temperature. 7 of 14 What are some factors that are involved in regulating the rate of heat exchange between an animal and its environment? Factors include temperature difference, exposed surface area and efficiency of insulation 8 of 14 How do endothermic animals retain heat? Endothermic animals retain heat using insulation and behavioural mechanisms. 9 of 14 What does insulation do? Insulation reduces heat exchange with the environment. 10 of 14 How do most animals regulate heat exchange? Most animals use behaviour to regulate heat exchange. An example could be physically moving to a different environment. 11 of 14 What does heat production require? Heat production requires a lot of energy, which requires a lot of food. 12 of 14 What are some plant adaptations to reduce water loss? Sunken stomata, structure and orientation of leaves. 13 of 14 What are disturbance detectors? Detect change in the external environment before they affect core body temperature. 14 of 14
