NEET Botany (general) MCQ Question
Which of the following combinations correctly describe the characteristics of detritus food chains and their components?
Detritus food chains begin with dead organic matter and are primarily composed of decomposers.
Decomposers in detritus food chains are autotrophic organisms that produce energy from sunlight.
Detritus food chains rely on the decomposition of organic matter by saprotrophs to release inorganic nutrients.
Detritus food chains are less important in terrestrial ecosystems compared to grazing food chains.
Correct Answer
Detailed Explanation
Detritus food chains start with dead organic matter and are made up of decomposers, which are heterotrophic organisms that degrade this organic matter. Option B is incorrect because decomposers are heterotrophic, not autotrophic. Option C is correct but not a combination with A. Option D is incorrect as detritus food chains are more significant in terrestrial ecosystems.
