Fungal Ecology: Decomposers and Nutrient Cycling
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Fungi act as major decomposers, breaking down dead matter and releasing nitrogen, phosphorus, and other elements back into an ecosystem.
Show
A shelf fungus growing on a fallen tree digests its wood over years, returning locked nutrients to the surrounding soil.
Watch for
Without fungal decomposers, nutrients like nitrogen would stay locked in dead matter, unavailable to the rest of an ecosystem.
