Some microorganisms like bacteria and fungi break down the dead bodies ino simpler substances, are called decomposers.
magine this scene... bodies are piled high, everything from birds and mammals to lizards and frogs. Mixed in are leaves, branches, feces, and even dead people. The stench is overwhelming. You try to turn away, but you are surrounded. It sounds like a horror movie, but at this show, you can't even have a grilled cheese sandwich with a glass of wine while watching the horrors unfold. Where are you? In a world without decomposers.
It may be unpleasant to think about, but decomposers do the natural world's dirty work. They are responsible for eliminating dead and dying organisms, and in the process, they release nutrients into the soil.
