What is hibernation & aestivation?
This sleeping pattern is divided into two subtypes, hibernation and aestivation. Hibernation happens during the winter season. Here animals stay in dormant condition during low temperature. On the other hand, aestivation occurs during the summer season. During high temperature, animals stay inactive to save energy.
What is the difference between hibernation and Brumation?
Hibernation is a deeper and longer version of torpor. Brumation, on the other hand, is specific to reptiles and amphibians that enter a state of ‘deep sleep’ where they undergo the same process of inactivity and low body temperature, heart rate, metabolic rate, and respiratory rate drops.
Which of the following is an example of hibernation in beer and aestivation in fishes?
Complete answer:
| Hibernation | Aestivation |
|---|---|
| It takes place for a long duration. | It takes place for a quite smaller duration. |
| Bears and squirrels hamper cold regions are examples of animals that hibernate throughout winters. | Fishes and snails are examples of organisms aestivating throughout summers. |
What is hibernation Class 12 example?
Hibernation or winter sleep is a resting stage where in animals escape winters (cold) by hiding themselves in their shelters. They escape the winter season by entering a state of inactivity by slowing their metabolism. The phenomenon of hibernation is exhibited by bats, squirrels, and other rodents.
What are the two types of hibernation?
There are two types of hibernation: obligate hibernation and facultative hibernation. Obligate hibernators can sleep regardless of access to food and ambient temperatures. Facultative hibernators hibernate when it’s too cold and food supply has reduced.
What are the signs of Brumation?
Your Beardie can show signs of brumation at any time, but they typically show the following signs when their tank’s temperature is decreased:
- Eating less.
- Sleeping more.
- Spending more time in a hide.
- Staying out of the basking spot.
- Staying out of direct light.
- Moving slower than normal.
What is hibernation give example?
Hibernation is a type of deep sleep some animals (like bears) go into during winter. For example, you could talk about the hibernation of an athlete who has taken a year off from competition.
What is hibernation very short answer?
Hibernation is when an animal slows its heart rate to save energy and survive the winter without eating much. Some animals just slow down and move less frequently during hibernation, but others go into a deep sleep and don’t wake up till spring. The brown fat forms patches near the animal’s brain, heart and lungs.
What’s the difference between aestivation and hibernation?
Aestivation is the type of summer sleep, performed by cold-blooded animals. It is for the whole winter. It is of short duration. As hibernation is the sleep during the winter, the animals look out for the warmer place, their metabolic activities slow down, and it is the dormant stage.
What’s the difference between hibernation and summer sleep?
The state of inactivity and a low metabolic process performed by the animals during the winters is known as Hibernation. It is also known as winter sleep. On the contrary, when animals take rest in shady and moist place during summer, it is called as hibernation. Hibernation is also known as summer sleep.
Why do animals go into hibernation in winter?
Hibernation is a situation where certain animals go dormant completely during winter by lowering their metabolic activity. The phenomenon is also known as winter sleep. These animals eat a lot of food and store them in the form of fat. This helps to combat the shortage of food during winter.
What’s the difference between aestivation and estivation?
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. The importance of these sleep is mainly related to the conservation of energy of one’s body, survival during the extremes temperature, scarcity of food and water, etc.
