The decomposition is a process that occurs when the organisms are dying. The process stars shorty after the death of the organism. The decomposition occurs by abiotic and biotic processes, with the abiotic happening through hydrolyses, while the biotic happening because of the microorganisms. This process is part of the nutrient cycle, and it is crucial for the recycling of the finite matter. The decomposition is also what has enabled the formation of the soils, as the soils are a mixture of sediments and decomposed biomass.
