• A. 1 & 2
• B. 2 & 3
• C. 1 & 3
• D. All are correct

Answer 1

Answer:

C. 1 & 3

• Correct Answer: Option C) 1 & 3

• Ecosystem represents both structure and function of nature. - This statement is correct. An ecosystem encompasses both the structural components (various organisms and their physical environment) and the functional aspects (energy flow, nutrient cycling, and interactions between organisms and their environment).

• It includes only living organisms interacting with one another. - This statement is incorrect. An ecosystem includes both biotic (living) and abiotic (non-living) components. The interactions occur not just between living organisms but also between organisms and their physical environment (soil, water, air, temperature, etc.).

• It is the smallest unit of environment that includes both biotic and abiotic factors. - This statement is correct. An ecosystem is indeed considered the smallest functional unit of ecology that contains both living organisms and their non-living environment interacting as a system.
