Question

Assertion (A): Food web is a network of several food chains operating in an ecosystem. 
Reason (R): Food web decreases the stability of an ecosystem.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

A food web improves ecosystem resilience, as it reduces the impact of species loss on the overall balance of the ecosystem.

Answer 1

The Correct Option is C

Step 1: Understanding Food Web. A food web is a network of interconnected food chains within an ecosystem, illustrating how different species are related through feeding. 
Step 2: Analyzing Reason (R). Food webs actually increase the stability of an ecosystem by providing alternative pathways for energy flow, meaning that if one species declines, others can take its place. 
Step 3: Conclusion. Since Assertion (A) is true but Reason (R) is false, the correct answer is option (C).
