Answer 1

The correct option is D

all of the above

Correct option is (D):
Explanation for correct option:

1. Extinct organisms are those animals whose existence is no longer there in the world. They have totally vanished from the globe and the ecosystem.
2. There is a sudden change in the climate: The reason behind extinction is the cutting of trees by humans for their needs, which is the natural home of flora and fauna. This introduces global warming, greenhouse gases emission and leads to the dispersal of animals to other areas and disappearance of the fauna residing in them.
3. Their habitat is destroyed by human beings: The increasing population has exerted a lot of pressure on forest land and due to their exploitation of this area for building homes, markets and other such things, animals are forced to leave their home.
4. Animals are hunted for sport: Animals are excessively killed by poachers for food, fur and sports.

Final answer: Plants and animals become extinct because of habitat lost by human activities, hunting for fur and sports, and sudden changes in the climate.
