Scenario To Study the Effect of Ambient (Environmental)temperature on the Metabolic

Multiple Choice

Scenario
To study the effect of ambient (environmental) temperature on the metabolic rate of animals, a scientist takes a small animal and puts it in a sealed chamber with oxygen. The scientist measures the amount of oxygen used by the animal at different temperatures, as oxygen is consumed during the process of cellular respiration. The temperatures selected are those that the animal normally encounters in nature. The data from this experiment are in the table below.

-The scientist studies a second animal whose oxygen consumption rises as temperature increases. The second animal is most likely to be ________.

A) an ectotherm
B) an endotherm
C) one that cannot osmoregulate
D) one that primarily uses metabolism to regulate temperature
