Signed, Angie - Central Elementary School. The worst thing about bread mold is not knowing it's there until after your first bite. Bread mold is caused by a fungus.
Fungi are types of organisms that eat old, decaying, organic matter.
They are not plants or animals. Fungi are important to our environment because they eat and decompose trash and other stuff that we no longer use. In fact, if it weren't for fungi, we would be up to our armpits in junk. Because fungi basically destroy stuff, we might consider them bad. They create mold on our food, they spoil meat, and they can cause diseases on plants and animals.
