NEET Botany (general) MCQ Question
In a terrestrial ecosystem, if 1000 kcal of energy is captured by plants through PAR, how much energy would be expected to flow through the detritus food chain?
500 kcal
300 kcal
700 kcal
100 kcal
Correct Answer
Detailed Explanation
According to the NCERT context, a much larger fraction of energy flows through the detritus food chain than through the grazing food chain in a terrestrial ecosystem. If 1000 kcal is captured, it is plausible that about 50% (500 kcal) flows through the detritus food chain.
