Decomposers and Transformers are the living components of the ecosystem and they are fungi and bacteria. Decomposers attack the dead remains of producers and consumers and degrade the complex organic substances into simper compounds. The simple organic matters are then attacked by another kind of bacteria, transformers, which changes these organic compounds into the inorganic forms that are suitable for re-use by, producers or green plants. The decomposers and transformers play very important role in maintaining the dynamic nature of ecosystems.
