Answer:

Explanation:

Moulds grow in dark,warm and moist place. Moulds are fungi and there spores are already present in air. And ur food i.e.bread in this was not sterile(germ free) and therefore spores from air came in contact with bread....and no harsh air flow is allowing it to grow and set it's hyphae.
