A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms. In the carbon cycle, decomposers break down dead material from plants and other organisms and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. Although anaerobic decomposition initiates within the animal, it may continue to proceed outside of the animal, if the plastic bag remains intact and when the aerobic organisms have depleted the available oxygen inside the bag. The nutrients flow through the water and the water helps . But calcium is only found in the eggshells, not the inside of the eggs. This is called decomposition . Yes!
