Which microorganisms are interlinked between living and non-living forms?

Some examples of microorganisms that are interlinked between living and non-living forms include certain types of bacteria that can facilitate nutrient cycling between organic and inorganic matter in the environment. For instance, nitrogen-fixing bacteria can convert atmospheric nitrogen into a form that plants can use, thus forming a vital link between living plants and the non-living nitrogen in the air. Additionally, certain types of fungi play a role in decomposing organic matter and releasing nutrients back into the soil, bridging the gap between living and non-living components of ecosystems.
