Question

Which of the following is not characteristic of an ecosystem?

• A. Energy flow
• B. Nutrient cycling
• C. Decomposition
• D. Dominant species

Answer 1

The correct option is D Dominant species

Ecosystem is formed by the interaction of biotic and abiotic components present in the environment. The characteristic productivity, decomposition, energy flow, and nutrient cycling come under the functions of an ecosystem. While the dominant species is just a part of the ecosystem, it is not by itself a characteristic, which plays an important role in the functional aspect of the ecosystem.
