NEET Botany (general) MCQ Question
Which of the following statements about decomposition and ecological pyramids is correct?
Decomposition is primarily an anaerobic process enhanced by high lignin content in detritus.
The rate of decomposition is influenced by the chemical composition of detritus and climatic factors.
Ecological pyramids illustrate only the biomass at the bottom trophic levels, ignoring higher levels.
Decomposers do not contribute to nutrient cycling within an ecosystem.
Correct Answer
Detailed Explanation
The rate of decomposition is indeed influenced by the chemical composition of detritus and climatic factors, as stated in the NCERT context. Option A is incorrect because decomposition is largely an aerobic process, while option C misrepresents ecological pyramids, and option D overlooks the crucial role of decomposers in nutrient cycling.
