Once the detritus is broken up and the water-soluble nutrients have been taken out, the decomposing fungi and bacteria release enzymes that break down the rest of the detritus. Bacteria help recycle important nutrients like nitrogen, carbon, and others so that they can be used by the producers in the food chain. Numerous different types of decomposers are involved at any given type in the decomposition of dead organic matter. Christmas tree worms use their feathery appendages to catch organic matter that floats in the air. Fragmentation means the breakdown of detritus into smaller pieces by the detritivores. Abiotic factor comprises non-living components like sunlight, temperature, water, soil, wind, humidity and radiations. Decomposition plays an important role in many ecosystems as it is through this process that nutrients are recycled from one form to another in a cycle known as the nutrient cycle.
