Are decomposers break down detritu which is living organic matter?

Decomposers break down detritus, which primarily consists of dead organic matter rather than living organic matter. This material includes fallen leaves, dead plants, and animal remains, providing essential nutrients to the soil. By recycling these nutrients, decomposers play a crucial role in maintaining ecosystem health and promoting new plant growth. Thus, they are vital for the nutrient cycle but do not act on living organisms.
