A)Measure the animal's body temperature,and compare it to ambient temperature at various times throughout the day and night.
B)Determine the animal's urine production,and compare it to ambient temperature at various times throughout the day and night.
C)Measure the animal's rate of oxygen consumption,and compare it to ambient temperature at various times throughout the day and night.
D)Observe the animal's behavior and activity level,and compare it to ambient temperature at various times throughout the day and night.

Determining the animal's urine production and comparing it to ambient temperature is not directly related to whether the animal is an ectotherm or an endotherm. Options A, C, and D are all helpful methods for determining whether the animal is an ectotherm or an endotherm. Measuring the animal's body temperature can help determine if it is regulating its own temperature (endothermic), or if it is the same as the surrounding environment (ectothermic). Similarly, measuring the animal's rate of oxygen consumption can provide insight into its metabolic activity and therefore, whether it is an endotherm or an ectotherm. Observing the animal's behavior and activity level can also provide clues as to whether it is regulating its body temperature or relying on the environment.
