Decomposers

Bacteria are among the main decomposing organisms, i.e. they degrade organic substances and release in the environment simple molecules that can be used by the other living beings. They play an essential role: without decomposers, the substances that make life possible would no longer be available in the environment. Some bacteria, the nitrifying ones, demolish proteins and release nitrogen-rich compounds, others release phosphor, sulphur and other useful substances.
