An inactive state resembling deep sleep in which certain animals living in cold climates pass the winter. In hibernation, the body temperature is lowered and breathing and heart rates slow down. Hibernation protects the animal from cold and reduces the need for food during the season when food is scarce.

What is hibernation and aestivation Mcq?

Solution(By Examveda Team) Aestivation is summer sleep and during aestivation, animals usually tend to rest in a shady and cool place. They take sleep during the hot hours of daytime.

What is the difference between hibernation aestivation and Brumation?

Brumation is known as the hibernation for cold-blooded animals. Cold-blooded animals will move on warmer winter days and find water, unlike hibernators who are in a deep sleep and do not move at all. Estivation is when animals are dormant because weather conditions are very hot and dry.

What is Aestivation example?

In aestivation, animals look for moist and cool locations. Some of the animals that undergo hibernation include insects, birds, mammals, and bats. The animals that undergo aestivation include earthworms, frogs, bees, snails, salamanders, tortoises, and crocodiles.

What is called hibernation?

Hibernation is a way for many creatures – from butterflies to bats – to survive cold, dark winters without having to forage for food or migrate to somewhere warmer. Instead, they turn down their metabolisms to save energy. Animals in hot climates also undergo a form of hibernation called aestivation.

What is Aestivation explain its types?

Hibernation is an extended form of torpor, a state where metabolism is depressed to less than five percent of normal. This is very different from sleep, which is gentle resting state where unconscious functions are still performed.

What is the difference between aestivation and hibernation?

Difference Between Aestivation And Hibernation Hibernation or “winter sleep” is the state of inactivity or low metabolic process performed by the animals during winters. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summers.

What is the difference between aestivation and estivation?

It is also known as winter sleep. On the contrary, when animals take rest in shady and moist place during summer, it is called Aestivation or Estivation. Aestivation is also known as summer sleep.

Why do animals hibernate in the fall?

Therefore, they go through a process called hibernation. Hibernation is when some animals have long periods of deep sleep during cold weather. To help them prepare, hibernating animals eat lots of food during the fall so they can survive the cold and dangerous winter.

What is aestivation in plants?

Additionally, aestivation in plants is also present, such as guava. The dormant state of hibernation is witnessed in animals during the winter season. Therefore, it is called winter sleep. On the other hand, the inactive state of aestivation occurs during the summer. Thus, it is called summer sleep.
