DENDROLOGY

Detailed explanation-1: -Animals in very cold regions go into a state of inactivity or “sleep” to conserve energy during winter.

Detailed explanation-2: -Bears are the animals most known for hibernating, but they aren’t the only ones. Turtles, snakes, wood frogs, and groundhogs are other animals that engage in some form of hibernation, torpor, or estivation. Take a look at some of the animals that like to hide until spring arrives.

Detailed explanation-3: -Hibernating animals slow their metabolisms, cooling their bodies by 5° to 10°C (9° to 18°F). Arctic ground squirrels (Spermophilus parryii) can take this much further, cooling their bodies to subfreezing temperatures.
