Question

please, if anyone can help me with this

1) Below is a graph of the metabolic rate (kcal/day) as a function body mass for five groups of species. Study the plot carefully and look to see the axes are log scale. Check the units of the axes and then answer the following questions. a) What is the metabolic rate in watts) of a non-passerine bird of 200 g? b) What group has the highest metabolic rate at a giving body mass? c) What is the metabolic rate (in watts) of a 0.5 kg lizard at 37°C 2 d) How much greater is the metabolic rate in watts) of a 10 g passerine bird than of a 10g lizard at 37°C. Please answer as a ratio. i.e. A statement such as the mebolic rate of the bird is Xtimes greater/less than the lizard? e) What is the answer if the comparison is between a 1 kg passerine bird and a 1 kg lizard at 37°C ? How does this compare with your answer in c. What do you make of the difference? 1 If oxidizing one mole of glucose yields 673 kilocalories, how long could a 10 g and I kg passerine bird survive, assuming each has energy stores equal to 10% of their body mass in glucose. What would be survival time for lizards at 10 g and I kg with the same energy supply? (Given their metabolic rates how many days can they live?)

information should be from the graph

From the graph we get, Metabolic hat Reallday) of a non possesive bind weighing 200g = 25kcal/day As Ikcoll day = 0.0484 watts Hemce Metabolite o biods250.0484 = 12 watts Passerine birds have the highest rate because log lizard has metabolic rate 0 0.65 kcal/day, 109, Yonal w as how metabolic State 9 1.25 kcal day placental mammals have metabolic sad 2 Now pass thini birds have metabolic rate: 2. 5 d , and passerine birds of some mass have meta- - bali hate Skoallay which is the highest From the graph we get Metabolic arre (kcal day) of lizard weighing 0.5kg = 7 keallady As I kcall day = 0. Ougtu watts Hence Metabolic ante = 7X0.0484 - 0.3384 Watts

PAGE NO (dll from the b bart we know, Metabolic rate ok log lizard = 0.65 kcalldan its - 0.65X 0.0484 Wate Metabolic rate og basserine bird 5kcality gu watesa sxo.0484 Watts Ratio of - Metabolic Rates Metabolic Rate of bird Metabolic Rate of lizard = 5X 0.0484 0.65X0 0484 = 7.69 Metabolic Rate of Passerine bird is 7.69 times greater than of lizard
