Question
UPSC Prelims 2014 Question:
Consider the following:
- Bats
- Bears
- Rodents
The phenomenon of hibernation can be observed in which of the above kinds of animals?
Answer (Detailed Solution Below)
Option 3: 1, 2 and 3
Detailed Solution
Explanation:
- Hibernation is a state of greatly reduced metabolic activity and lowered body temperature adopted by certain mammals as an adaptation to adverse winter conditions. They spend most of the winter sleeping in dens.
- Among mammals, true hibernators are found only in the orders Chiroptera (bats), Insectivora (hedgehogs and allies), bears and Rodentia (ground squirrels, marmots, etc.). Typically, the hibernator relies on a combination of reserve body fat, stored food supplies (in rodents only), and a protected den to enable it to survive the winter. So, points 1, 2 and 3 are correct.
Therefore, option (3) is the correct answer.
