Why mold is in the toilet?

​MOLD IN TOILET: WHAT CAUSES IT?We must first understand that mold is a fungus. Mold spores and mildew grow in dark, humid places (such as the bowl and tank). When you’ve been away for even a few days on vacation, black mold may be seen in your toilet bowl or tank.
Because mold thrives in damp and dark places, your toilet bowl and tank are ideal breeding grounds for it. If you don’t have proper ventilation or exhaust fans in your bathrooms, these damp and dark places can help create the ideal environment for mold growth.
