• Hibernation. Hibernation is the second strategy to surviving cold temperatures. ... The animal will generally curl up into a tight ball to help keep warm, body temperature drops, and respiration and heart rate slow down.

Answer 2

Answer:

Hibernation

Hibernation is the second strategy to surviving cold temperatures. Hibernation is long-term dormancy, or inactivity, while “torpor” is the term to describe short-term inactivity. The definition of hibernation from National Park Service’s “Winter Ecology Teacher’s Guide” is “…a physical state where an animal’s body function slows down in order to conserve energy through a season of no food and water, and cold temperatures.” This slower body function is characterized by a decrease in body temperature and reduced respiration, or breathing. The animal will generally curl up into a tight ball to help keep warm, body temperature drops, and respiration and heart rate slow down. These actions reduce the amount of energy the animal must expend to stay alive so it’s able to live off of fat reserves it has developed instead of constantly having to seek out food.

Hibernation strategies exist on a continuum from “true hibernators” to a “deep sleep” and finally an “occasional sleep.” Examples of true hibernators are Columbian ground squirrels and marmots, both of which experience an extreme body temperature drop (90 degrees Fahrenheit normally versus 39 F while hibernating) and very slow respiration (a breath every four to six minutes). Bears, on the other hand, are in the deep sleep category because they do not experience the extreme body temperature drop; instead, they grow a thick hair coat before winter arrives. Raccoons and gray squirrels fall into the occasional sleep category because they generally stay active during the winter except for extremely frigid temperatures.
