Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept: An ecosystem includes both biotic (living) and abiotic (non-living) components interacting together.
• It is capable of self-regulation through feedback mechanisms.
• Energy flow and nutrient cycling make it self-sustaining.
Step 1: Analyze Statement I.
An ecosystem is indeed a structural and functional unit that is self-regulating and self-sustaining. Hence, Statement I is correct.
Step 2: Analyze Statement II.
The biosphere includes all ecosystems on Earth and functions as a global ecosystem. Hence, Statement II is correct.
Step 3: Conclusion.
Both statements are correct. Final Answer: Option (A)
