Question

A food chain in an ecosystem represents the __________________

• A. Biotic components only
• B. energy flow and transfer of nutrients
• C. Both (a) and (b)
• D. abiotic components and decomposers

Answer 1

The correct option is D abiotic components and decomposers

Transfer of food energy from the producers through a series of organisms with repeated eating and being eaten is known as food chain. The food chain consists of producers, primary consumers, secondary consumers, tertiary consumers or top carnivores and decomposers. Energy trapped by the producers are transferred to other organisms in the food chain. Therefore a food chain in an ecosystem represents both the feeding relationship and energy flow.
