Is blue mold in cheese living or nonliving?

Here's why:

* It's a fungus: Blue mold is a type of fungus called *Penicillium Roqueforti*.

* Fungi are living organisms: They are made of cells, reproduce, grow, and require nutrients to survive.

* Blue mold's role in cheese: The mold spores are introduced into the cheese during production, and they grow and develop within the cheese, contributing to its flavor and texture.

While blue mold is beneficial in some cheeses, it's important to remember that it's still a living organism.
