As the only organisms have the ability to break down lignin and are of great importance in the breakdown of cellulose, thanks to the specific enzyme - cellulase.
Fungi can be a source of both inorganic matter, which are products of metabolism (CO2, H2O), and organic matter, as they are food for many microbes. Thanks to fungi, the decomposition of branches and leaves occurs - it is estimated that without their activity, 12 tonnes of cellulosic waste per hectare would be created in tropical forests annually.
