Decomposition occurs either in aerobic or anaerobic, oxygen or oxygen-free, environments. In anaerobic environments, bacteria are the main decomposers, because the other decomposers require oxygen. The process usually takes longer with only bacteria to break down the organic matter.The primary decomposers are f<span>ungi, worms, protozoans, nematodes and soil bacteria.</span>
<span>two primary decompose-rs are fungis or (fungi) and bacteria. Their function in the recycling of life materials is very prominent because without them all organisms that died would decompose slowly. </span><span> </span>
