Textbook Question
Chapter 16, Problem 3CT
Fats are highly energy-rich molecules that require a great deal of energy to produce, but in the mesopelagic, where food is scarce, many fishes have swim bladders filled with fat. How might this be explained?

An average adult cheetah has a mass of 44,010 grams and a metabolic rate of 61.77 joules per
second. Use these data to place the cheetah on the graph. Based on these data, would you
characterize the cheetah as an endotherm or ectotherm? How do you know?
Why are fish living in cold waters particularly likely to have stores of unsaturated fats in their bodies, rather than saturated fats?
Mammals in the Arctic Circle such as reindeer have higher levels of unsaturated fatty acids in the cell membranes in their legs than in other parts of their bodies. Suggest a reason for this phenomenon. Does it have a survival advantage?
