From where organisms get energy and nutrients: Decomposers

\r\n \r\n\r\n

The biotic factors that use dead bodies of other organisms or waste materials produced by them for the energy and nutrients are called decomposers. Mainly fungus and bacteria work as the decomposers in every ecosystem and their activity is essential to avoid the degeneration of the ecosystem. They break down the dead materials into the abiotic factors and make it available to the producers.
