Question

ASSERTION: Animals adopt different strategies to survive in hostile environment
REASON: Praying Mantis is green in colour which merges with plant foliage.
A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C. Assertion is correct but Reason is incorrect.
D. Both Assertion and Reason are incorrect.

Answer 1

Hint:-
Adaptation is an organism's physical or behavioral trait that makes an organism survive in the surrounding environment better. Charles Darwin proposed the theory of adaptation.

Complete answer:
Animals adopt different strategies like camouflage and mimicry which help them in hiding to survive in an unfriendly environment.
DNA mutations help organisms in longer survival in dangerous environments and these traits of survival are passed onto the next generations. These adaptations make it possible for a variety of organisms to grow and develop on planet earth.
For example, the species of praying Mantis that are distributed worldwide in temperate and tropical habitats. They show a cryptic coloring body that allows them to adopt the color of their surroundings that helps them to blend in and to be unnoticed by other organisms, both prey, and predators. Some also have a body shape that makes them look like leaves or branches.
Therefore, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation of Assertion', option (B)

Note:-
For the survival of living organisms, adaptation is necessary. Animals who can not respond to adapt changes in the world die. These adaptations are a result of genetic variations. The animals that survive pass on the mutated traits to their off-springs. This process is known as natural selection. The theory of adaptation states that an organism that is able to adapt to the changing environment will survive, the rest will be eliminated. This is called the ‘survival of the fittest’.
