The  pair of statements best explains an environmental stimulus and a bear’s response to survive winter is  The bear senses that food is becoming scarce. The bear consumes less food, and its heart rate increases.
During hibernation, the animal's body remains inactive, its temperature drops considerably, and blood flow and heartbeat are reduced. The reduction in metabolism causes energy expenditure to be reduced and, consequently, these beings save nutrients.
In winter, food is very rare and the water in some rivers freezes. With no water and no food, the solution is to hibernate in a sheltered place until spring. When sleeping, bears use less energy. And they get the little energy and water they need from their own fat when they hibernate.
