Chemical Reactions and Equations
If there were no decomposers them the dead remains and waste would pile up. The nutrients would not be replenished. Natural enrichment of the soil would not take place. All the nutrient cycles have decomposers as their components. In their absence, these nutrient cycles would not be complete. There will be no recycling of matter between biotic and abiotic components of an ecosystem, because all the matter will remain locked up in the dead bodies. Thus existence of life on this earth would have been impossible.
