1.	Question : Describe how oxygen and chemical composition of detritus control decomposition do.
Answer» Solution :Decomposition is largely an oxygen-requiring PROCESS. The rate of decomposition is controlled by chemical composition of detritus and climatic factors. In a particular climatic condition, decomposition rate is slower if detritusis RICH in lignin and chitin, and quicker, if detritus is rich in NITROGEN and water-soluble substances like sugars. Temperature and soil moisture are the most IMPORTANT climaticfactors that regulate decomposition through their effects on the activities of soil microbes. Warm and moist environment favor decompositionwhereas low temperature andanaerobiosisinhibit decomposition resulting in buildup of organic materials.
