32. Suppose that you compare the amount of food needed by four groups of lizards, each of which has an MR that is expected for its body size. There are 10 lizards weighing 10 g each, 5 lizards weighing 20 g each, 2 lizards weighing 50 g each, and a single 100-g lizard. Assuming equal digestibility, similar food, and so on, the _______ lizards need themost food.a. 10-gb. 20-gc. 50-gd. 100-ge. All of the above need the same amount of food.© 2012 Sinauer Associates, Inc.
Answer: aTextbook Reference: Metabolic Scaling, p. 173Bloom’s Category: 3. Applying33. In which of the following cases would the equation M=aWbnotbe considered allometric?34. Suppose that a study reports the allometric equation relating whole-animal metabolic rate to body weight for a new group of organisms. Based on existing data for other groups, which value would you predict for b?35. Suppose the value of bfor the allometric equation for maximal metabolic rate (MMR)and body weight is 0.87. The exponent for the equation relating the mass-specific MMR to body weight would be36. Suppose that W(weight) has been measured in grams for groups of big and little eaters. Daily food consumption of big eaters is described by the allometric equation: food(g/day) = 5 W0.67. Daily food consumption of little eaters is described by the allometric equation: food (g/day) = 0.75 W0.67. Each day, a 1-g big eater will need _______ more compared to a 1-g little eater.a. 1 gb.

c. (4.25)0.67gd. 4.25 ge. None of the above; they will both need the same amount of food.Answer: dTextbook Reference: Metabolic Scaling, p. 174Bloom’s Category: 5. Evaluating37. Assume that the standard allometric equation (M= aWb) applies to a given species.Weight-specific metabolic rate will notdepend on weight when38. Suppose that you want to plot metabolic data for animals ranging in weight from 2 g to 10,000,000 g. A loglog plot would be useful becausea. data > 1,000,000 g or < 1 g cannot be plotted on other kinds of graphs.b. a loglot plot transforms an allometric equation into a curve.c. only a loglot plot makes it possible to plot carnivores and herbivores on the same graph.d. a loglog plot puts all animals (e.g., birds and frogs) on the same trend line.e. with a loglog plot a wide range of body weights can easily be plotted on the same graph.Answer: eTextbook Reference: Metabolic Scaling, p. 175Bloom’s Category: 1.
