Question

5 during hibernation, the ground squirrel may breathe every four minutes, its heart beats four times a minute, and its body temperature drops from a normal temperature of about 99 degrees to just above freezing. what is the purpose of hibernation? to reduce exposure to predators by remaining inactive underground to regulate body temperature in response to seasonal changes to conserve energy by slowing metabolic processes when resources are limited to allow physiological systems to reset before the spring breeding season

Explanation:

Hibernation in animals like ground squirrels involves slowing metabolic processes (e.g., reduced heart rate, body temperature drop) to conserve energy when food/resources are limited, typically in winter. Other options: reducing predator exposure isn't the main purpose (hibernation is more about energy), regulating temp is a mechanism not the purpose, and resetting physiological systems isn't the core reason. The option "To conserve energy by slowing metabolic processes when resources are limited" aligns with biological hibernation principles.

Answer:

To conserve energy by slowing metabolic processes when resources are limited
