(B) : Decomposition is the process in which decomposers break down complex organic matter into inorganic substances like carbon dioxide,water,and nutrients. The important steps in the process of decomposition are fragmentation,leaching,catabolism,humification,and mineralisation.Detritivores (e.g.,earthworm) break down detritus into smaller particles. This process is called fragmentation.By the process of leaching,water-soluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts.Bacterial and fungal enzymes degrade detritus into simpler inorganic substances. This process is called catabolism.Humification leads to the accumulation of a dark-colored amorphous substance called humus,which is highly resistant to microbial action and undergoes decomposition at an extremely slow rate.The humus is further degraded by some microbes,and the release of inorganic nutrients occurs by the process known as mineralisation.
