Question

Assertion: Exotic species introduced in an ecosystem out-compete native species for food and shelter

Reason: Natural predators of exotic species are absent in the ecosystem to which they are introduced

• A. Both the assertion and reason are true and the reason is the correct explanation of the assertion
• B. Both the assertion and reason are true but the reason is not the correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both the assertion and reason are false

Answer 1

The correct option is A Both the assertion and reason are true and the reason is the correct explanation of the assertion

When alien species are introduced unintentionally or deliberately for whatever purpose, some of them turn invasive and cause decline or extinction of indigenous species. Alien species are either praying on native species or out-competing native species for food and shelter in the absence of natural predators. Thus both the assertion and reason are true and the reason is the correct explanation of the assertion.
