Question:
Assertion (A): Species is an ecological unit.
Reason (R): It shares the same ecological niche.
Assertion (A): Species is an ecological unit.
Reason (R): It shares the same ecological niche.
Show Hint

- Both (A) and (R) are true. (R) is the correct explanation for (A)
- Both (A) and (R) are true. (R) is not the correct explanation for (A)
- (A) is true. But (R) is false
- (A) is false. But (R) is true
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
The definition of a species in an ecological context.
Step 2: Analysis
A species acts as a fundamental unit in ecology because its members are adapted to a specific ecological niche—the functional role and environment an organism occupies.
Step 3: Conclusion
Because members of a species share the same ecological requirements and niche, the species is classified as an ecological unit.
Final Answer: (A)
