Botany - Ecosystem Question with Solution | TestHub

Detritus consisting of remains of dead plant and animals are broken down by process of fragmentation into smaller particles by detrivores like earthworm. Detritus is also degraded into simpler inorganic substances by a bacterial and fungal enzymes by a process called as catabolism.By the process of leaching, watersoluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts. There is accumulation of a dark coloured amorphous substance called humus produced by a process of humification which is further degraded by some microbes resulting in release of inorganic nutrients by the process of mineralization.
