Question
What is INCORRECT about hibernation.
- Animals go into a deep sleep.
- Animals hibernate due to the unavailability of food.
- All animals hibernate during winter.
- Animals use up reserved fat during hibernation.
Hint:
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.
The correct answer is: All animals hibernate during winter.
Not all animals hibernate during winter. Only cold region animal hibernate to cope up with cold. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species.

______________ allows an organism to survive better in its environment
- Such changes occur in the organisms that helps them to survive better in the environment. This is called adaptation.
- These changes occur at genetic level and pass on to the next generation.
- These adaptations can be structural, behavioral or physiological.
- For example, most of the animals found in desert have a thick dermis layer on their body that assure minimum water loss.

Animals migrate because of:
- Animals migrate according to the season.
- The conditions of the place in a season becomes unfavorable.
- The animals can't survive or breed in such conditions, so they move to the other place. The distance of the travel can be around 25 miles.
- They migrate because of high or very low temperature conditions or unavailability of food.
- Bar headed geese migrate from Himalaya to south Asia in winter season.
- They travel 1000 miles.
- The condition of this place when becomes unfavorable they again move to the Himalayas.

The phenomenon in which animals go into a deep sleep is known as
- 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.
