  1. Movement of an organism or a group of organisms.

  2. Movement of natural habitat.

  3. Movement of an organism or a group of organisms from its natural habitat to another place at a particular time every year.

  4. All of the above.

Show answer
Correct Option: C
Explanation:

Migration is usually an annual event in which many animals travel to faraway places in search of food and breeding ground when climatic changes take place in their natural habitat. Many birds from Siberia come to India during winter months.

The habitat of an animal is disturbed

  1. Migration

  2. Extinction of that animal

  3. Both A and B

  4. None of the above

Show answer
Correct Option: C
Explanation:

The habitat of an animal provides it with necessities such as shelter, food, and protection. If the habitat of an animal is disturbed, then it will be forced to go to other places in search of food and shelter. The animal could get killed by other animals in this process and may become extinct in future.

Thus, the correct answer is option C.

Many birds from Siberia come to India, during winter months, in the search of

  1. Warm climate and food

  2. Cool climate

  3. Water availability

  4. None of the above

Show answer
Correct Option: A
Explanation:

The correct answer is 'warm climate and food'

Birds from Siberia such as the Siberian cranes come to India during winter months as they are cold-blooded animals and cannot survive in the extreme winters of their country. Food production and availability also reduces during winters making these the prime reasons for their migration to India.

Which one of the following statements are correct?
$1$. Migration leads to the redistribution of the population within a country.
$2$. Migration act as agents of social change.
$3$. Migration leads to segregation of people from diverse cultures.

  1. Only $1$ and $2$

  2. Only $1$ and $3$

  3. Only $2$ and $3$

  4. $1, 2$ and $3$

Show answer
Correct Option: A
Explanation:
 Migration is relocating from one country to another hence, there is redistribution of the population within a country. Migration acts as agents of social change as for example -new ideas regarding modern technology are diffused from urban to rural population because of migration.
So, the correct answer is 'Only 11 and 2'

Which of these animals migrate the farthest?

Correct Option: C

Which of the following conditions causes the extinction of species?

  1. Lack of flora

  2. Lack of favourable climatic condition

  3. High temperatures

  4. All of the above

Show answer
Correct Option: D

 .............. species are the species which face the danger of extinction due to the hard conditions to survive.

commercial applications environmental equilibrium threatened species need of conservation conservation of soil and wild life sleeping time animal senses sense organs in animals

  1. Threatened

  2. Extinct

  3. Migratory species

  4. All of the above

Show answer
Correct Option: A
Explanation:

Threatened species are the species which face the danger of extinction due to the hard survival conditions. Giant tortoise, African elephant, polar bear are some examples of threatened species. Extinct species are species who has died out. Extinction means no more individuals of that species is alive anywhere in the world. Passenger pigeon, black soft-shell turtle, Guam kingfisher are examples of extinct species. Migratory species are those animals that migrate to Australia or pass over Australian waters during their annual migrations. Whales, turtles, Monarch butterfly are some examples of migratory species. 

Thus, the correct answer is option A.

Which of the following are endangered species?

  1. Polar bears

  2. Giant pandas

  3. Rhinos

  4. All of the above

Show answer
Correct Option: D
Explanation:

Endangered species are those species which are at very high risk of extinction. Due to loss of polar bears' habitat which has resulted from climate change, they are considered as an endangered species. Due to habitat destruction and food shortage, giant pandas are also considered as endangered species. Rhinos are considered as endangered species because of rising demand for the horn of rhinos. 

Thus, the correct answer is option D.

Which of the following are an extinct species?

  1. Dinosaurs

  2. Tiger

  3. Elephant

  4. None of the above

Show answer
Correct Option: A
Explanation:

Extinct species are species who has died out. Extinction means no more individuals of that species is alive anywhere in the world. Passenger pigeon, black soft-shell turtle, Guam kingfisher, dinosaurs are some examples of extinct species. Endangered species are species who are at high risk of becoming extinct. Tiger and elephant are endangered species. 

Thus, the correct answer is option A.

Which of the following factors pose a threat to the species?

commercial applications environmental equilibrium threatened species need of conservation conservation of soil and wild life sleeping time animal senses sense organs in animals

  1. Lack of food

  2. Lack of rainfall

  3. Lack of natural resources

  4. All of the above

Show answer
Correct Option: D
Explanation:
Destruction of natural resources like forest may result in lack or removal of natural habitat for many species. Lack of food and rainfall affects the health of the species and may increase in the disease condition. All these pose a threat to the species and can result in extinction of species. 
Thus, the correct answer is option D.
