NEET Botany Energy Flow MCQ Question
Which of the following combinations correctly describe the flow of energy in an ecosystem?
Energy decreases at each trophic level and detritus serves as an energy source for decomposers.
Energy is constant across all trophic levels and only producers contribute to the energy flow.
Decomposers do not rely on detritus as an energy source and energy is recycled in ecosystems.
Each trophic level has a higher biomass than the one below it and energy flow is bidirectional.
Correct Answer
Detailed Explanation
The amount of energy indeed decreases at successive trophic levels, and dead biomass (detritus) serves as a crucial energy source for decomposers, as stated in the NCERT context.
