Directions: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion (A): Flow of energy in a food chain is unidirectional.
Reason (R): Energy captured by autotrophs does not revert back to the solar input and it passes to the herbivores.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?

Flow of Energy in a Food Chain

Assertion (A): Flow of energy in a food chain is unidirectional.
Reason (R): Energy captured by autotrophs does not revert back to the solar input and it passes to the herbivores.

To understand whether the assertion and reason provided are true or false, we need to analyze each statement separately and then evaluate their relationship.

Explanation of Assertion (A):
The assertion states that the flow of energy in a food chain is unidirectional. This means that energy moves in one direction only, from one trophic level to the next. In a food chain, energy flows from the producers (autotrophs) to the primary consumers (herbivores), then to the secondary consumers (carnivores or omnivores), and so on.

Explanation of Reason (R):
The reason provided states that energy captured by autotrophs (producers) does not revert back to the solar input and it passes to the herbivores (primary consumers). This is true because autotrophs are capable of capturing solar energy through photosynthesis and converting it into chemical energy in the form of organic compounds such as glucose. This energy is then transferred to herbivores when they consume the autotrophs as food. The energy does not revert back to the solar input because autotrophs utilize the energy for their own growth, reproduction, and maintenance.

Evaluation of the Relationship:
Both the assertion and the reason are true. The flow of energy in a food chain is indeed unidirectional, as energy moves from one trophic level to the next. The reason provided also correctly explains why the flow of energy is unidirectional, as energy captured by autotrophs is not reverted back to the solar input but instead passes on to the herbivores. Therefore, both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).

Conclusion:
Based on the analysis, the correct choice is option 'A', which states that both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
