How does fungi grow on food?
They grow from tiny spores that float around in the air. When some of these spores fall onto a piece of damp food or other materials they grow into molds. … A mold produces chemicals that make the food break down and start to rot. As the food is broken down into small simple parts the mold absorbs them and grows.
