You are planning a careful study of the metabolic rate of a spotted bat (Euderma maculatum). At the last minute, you learn that you will not be able to measure caloric intake directly. Should you abandon your study?
A. No, because oxygen intake can be measured instead, and it will provide an indirect measurement of metabolic rate.
B. No, because digestive enzyme production can be measured instead, and it will provide an indirect measurement of metabolic rate.
C. No, because water intake can provide an indirect measurement of metabolic rate.
D. Yes, because caloric measurement would provide the only meaningful data.
E. No, because carbon dioxide intake can be measured instead, and it will provide an indirect measurement of metabolic rate.
