Question

Animals migrate because of:

  1. Unavailability of food or water resource

  2. Extreme temperatures

  3. Inadequate conditions to reproduce

  4. All of the above

hintHint:

Some animals locate from a particular place to the other one this is called migration.

The correct answer is:

All of the above


    So, option 4 is the correct option. Because animals migrate to avoid all of the unfavorable conditions like unavailability of food and water, high or low temperature or to breed.

    • 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.

    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.
