Mushrooms, yeast and mould.
Where do fungi get their nutrients from?
Fungi get their nutrients from dead or dying matter such as fallen trees and dead leaves. They break this material down so it doesn’t pile up.
What is decomposition?
Decomposition is the breaking down of dead or dying matter to stop it from piling up.
Where can fungi grow?
Fungi can grow in dense forests, cold refrigerators and between people’s toes but they prefer warm, moist conditions like forests.
How do fungi reproduce?
Fungi reproduce by producing spores which are carried through the air by wind or other organisms. More spores = more of a chance that the spores will land in an environment that will support growth. If the environment supports growth, the spore can germinate (grow) to produce a new fungus.
What can cause fungal infections in humans?
Spores which land on your body can cause fungal infections in humans.

People who have weak immune systems and those who are taking certain medications (like antibiotics) have a higher risk of getting fungal infections.
