Decomposition & Nutrient Cycling — NEET Biology
📚 Practice ConceptDefine decomposition and describe the processes and products of decomposition.
Which of the following statements correctly describe the consequences of varying decomposition rates and the characteristics of its products? S1: A decrease in the rate of decomposition due to low temperature leads to a build-up of organic materials. S2: Detritus rich in lignin and chitin will decompose faster than detritus rich in nitrogen. S3: Anaerobic conditions enhance the process of humification, leading to the rapid breakdown of complex organic matter. S4: Humus, being resistant to microbial action, accumulates more readily under conditions that inhibit overall decomposition. S5: Mineralisation, the release of inorganic nutrients from humus, would be accelerated in cold, anaerobic environments.
