Question
The phenomenon in which animals go into a deep sleep is known as
- Mimicry
- Camouflage
- Migration
- Hibernation
Hint:
Animals show behavioural adaptation to survive in the environment.
The correct answer is: Hibernation
So the correct option is option 4. Because the phenomenon in which animals go into a deep sleep is called as hibernation.
- Hibernation and aestivation are also types of behavioural adaptation.
- During winters animals show hibernation.
- They avoid normal activities like hunting or roaming.
- Also they slower their metabolic rate, heart rate and breathing rate.
- So that they can save their energy.
- Most of the bears and snakes go into a deep sleep.

Camels can drink up to how many liters of water in one go?
- Camel is found in the desert.
- The temperature is around 50 C during summer.
- There is a lesser availability of food and water. The environment is also dry.
- So the camel has to survive in such conditions and it shows many adaptations like it can live without drinking water for 7 days.
- It can live for a maximum of 15 days without drinking water.
- It can drink around 100 to 200 water once.
- The water is stored in its blood.
- Also in the hot temperature, it is required to resist water loss.
- So, they do not sweat much and due to low metabolism, their body temperature is lesser.

Arctic foxes living in polar regions show which adaptation?
- The Arctic fox is found on ice packs
- They show many adaptations to survive in the cold environment.
- They have grey or brown fur.
- They can change the colour of fur according to the season.
- During winter their coat colour is white.
- When summer starts the white fur sheds and a thin grey coat covers its body.
- Later the grey fur becomes brown.
- So, this is how the arctic fox show camouflage.
- This helps in blending with the colour of the environment so that it can hide from the prey and can easily hunt.
