Fungal Ecology: Decomposers and Nutrient Cycling
Captions available
The idea
Fungi act as major decomposers, breaking down dead matter and releasing nitrogen, phosphorus, and other elements back into an ecosystem.
In practice
A shelf fungus growing on a fallen tree digests its wood over years, returning locked nutrients to the surrounding soil.
Where people slip
Without fungal decomposers, nutrients like nitrogen would stay locked in dead matter, unavailable to the rest of an ecosystem.
