Question:
Following components of the ecosystem are all linked to function as an 'ecosystem unit' EXCEPT ________
Following components of the ecosystem are all linked to function as an 'ecosystem unit' EXCEPT ________
Show Hint
Productivity, decomposition and energy flow are functional processes; one option describes structure.
Updated On: Nov 13, 2026
productivity
decomposition
stratification
energy flow
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
An ecosystem works as a unit through four functional processes: productivity, decomposition, energy flow and nutrient cycling.
Step 2: Check the options
Productivity, decomposition and energy flow are all functional components.
Stratification is the vertical layering of species, which is a structural feature of the ecosystem.
Step 3: Conclusion
Stratification is the exception.
Final Answer:
Stratification is not one of the functional components. \[ \boxed{\text{(C) }\text{stratification}} \]
