Question

A food chain is a series of a population, which starts with producers. It is concerning with ___ .

• 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 C

Both (a) and (b)

Transfer of food energy from the producers through a series of (biotic components) organisms with repeated eating and being eaten is known as food chain. Producers utilize the solar energy and transformed it to (biotic component) chemical form (ATP) during photosynthesis. Food chain involves biotic components and helps in energy flow and transfer of nutrients. Option 4 includes decomposers and abiotic components. Decomposers can be a part of the food chain but abiotic components are not a part of food chain.
