Q3. Hibernation is a period of long-term sleep that animals go into during winter. How is hibernation
similar to seed dormancy?
Answers
Explanation:
Hibernation is a state of minimal activity and metabolic depression. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months.

Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears[1] and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilize similar mechanisms.[2][3] The equivalent during the summer months is aestivation.
Answer:
Seed dormancy is the inability of viable seeds to germinate even under suitable environmental conditions, whereas hibernation in animals is a state of reduced activities to escape cold winter conditions.
Explanation:
Similarly, hibernation is a type of dormancy, but not all dormant animals hibernate. That's because hibernation is a really specific kind of dormancy. Dormancy describes an animal that has slowed down its bodily functions for a little while, but hibernation has some very specific rules.
