Detritus refers to small pieces of organic or inorganic material that have broken down or decomposed. This can include things like fallen leaves, dead plants, and animal remains, as well as fragments of rocks and minerals. In ecosystems, detritus plays a crucial role as it provides nutrients for soil and supports various organisms, such as decomposers like bacteria and fungi. In a broader context, detritus can also describe waste or debris resulting from human activities. This includes litter, discarded materials, and other remnants that accumulate in the environment. Managing detritus is important for maintaining clean habitats and reducing pollution in areas like urban environments and natural landscapes.
