The Correct Option is A
Solution and Explanation
Step 1: Understanding the term “functional unit of nature”.
The functional unit of nature refers to the smallest natural system in which living organisms interact with each other and with the physical environment.
Step 2: Role of an ecosystem.
An ecosystem includes biotic components (plants, animals, microorganisms) and abiotic components (air, water, soil), and allows energy flow and nutrient cycling.
Step 3: Analysis of options.
(A) Ecosystem: Correct — it is the basic structural and functional unit of nature.
(B) Food chain: Incorrect — it represents only a pathway of energy transfer.
(C) Ecology: Incorrect — it is the study of ecosystems, not a unit.
(D) Food web: Incorrect — it is a network of food chains within an ecosystem.
Step 4: Conclusion.
The functional unit of nature is the ecosystem.
