Final answer:
A hibernating homeotherm is an organism that enters a state of torpor over a long period of time, such as winter, in order to conserve energy. During hibernation, the body temperature of the organism decreases, which helps reduce metabolic rate and conserve energy.
Step-by-step explanation:
A hibernating homeotherm is an organism that enters a state of torpor over a long period of time, such as winter, in order to conserve energy. During hibernation, the body temperature of the organism decreases, which helps reduce metabolic rate and conserve energy. The blood pH of a hibernating homeotherm does not necessarily decrease, and the carbon dioxide levels in the blood may actually increase as a result of decreased respiration rate. However, the heart rate of a hibernating homeotherm typically decreases. Increased exercise is not a characteristic of hibernation.
