Explain the difference between autotrophic organisms and heterotrophic organisms.
Question 1. Explain the difference between autotrophic organisms and heterotrophic organisms.undefinedQuestion 2. If there is an "energy advantage" for organisms which use aerobic respiration, do you suppose this could explain why there are more aerobic species than anaerobic species? Explain your answer.undefinedQuestion 3. Assuming that an animal loses heat to its environment from its surface, suggest an evolutionary explanation for the following question: why do arctic hares have shorter ears than those of San Diego County jackrabbits?undefinedQuestion 4. Which animal taxonomic groups include endotherms?undefinedQuestion 5. What is an ectotherm? Give examples of animals which are ectotherms.undefinedQuestion 6. As the size of the cubes got smaller and smaller, what happened to the surface area : volume ratio?undefinedQuestion 7. Examine Figure 1. For each visible cube in the whole "organism", count the number of sides exposed to the outside. Write these numbers on the cubes in the diagram. Is there a cube with no sides exposed to the environment in Figure 1?undefined undefined undefined undefined undefined undefinedQuestion 8. Locate the cube marked "a" in each of the three figures on page 6. Compare cube "a" in the three figures: how many sides of each "a" cube are actually exposed to the outside surface?undefined Cube "a" Number of Sides Exposed Figure 1. 3 x 3 x 3 Figure 2. 2 x 2 x 2 Figure 3. 1 x 1 x 1 undefinedQuestion 9. Referring the Question 8, if each cube "a" were an equal amount of living tissue, which one would lose heat to a cooler environment fastest?undefined undefined undefinedQuestion 10. Referring to Question 8, if each cube "a" were an equal amount of living tissue, which one would need the fastest heat production to maintain homeostasis of its body temperature? (Remember, Cubus quadrangularis is a mammal.)undefinedQuestion 11. As an animal grows larger, what do you expect to happen to its rate of heat production per gram of body mass?undefined undefined undefinedQuestion 12. Based on the reasoning above, you will formulate a hypothesis for the following experiment. Small mice, medium-sized rats and large rats are available in the laboratory. We will measure their rate of oxygen uptake per gram body mass. undefinedWhat is the dependent variable we will measure?undefinedWhat is the independent variable?undefinedWhat are the groups being compared?undefinedNow, write the entire formula using the If…, and…, then… format.undefinedQuestion 13. Which mammal do you expect to have the fastest oxygen uptake per gram body mass? Explain why.undefined undefinedTable 1.

Based on the class data, describe the relationship which appears to exist between a mammal's size and its metabolic rate.undefined undefined undefinedQuestion 15. Has your hypothesis been supported by the class data?undefinedIf not, where did your reasoning go wrong?undefinedQuestion 16. Which would you predict to be higher, the metabolic rate of a sparrow or that of a gull? Explain your answer in terms of thermoregulation.undefined undefinedQuestion 17. To what extent do you think it would be valid to apply this "metabolic rate to body size relationship" to animals other than mammals (clams, insects, fish, frogs, reptiles and birds)? Explain.undefinedQuestion 18. Is there a thermoregulatory advantage for marine mammals such as whales to be so large? Explain your answer.undefinedQuestion 19. Suggest a reason why there are no rat-sized marine mammals.undefinedQuestion 20. If an animal is an ectotherm, which is without internal physiological thermoregulation, how does it manage to survive when the weather is very hot or very cold? Give an example.
