Moulds grow on organic materials because mould is a fungi, which feeds off the chemicals in the food.

-----------------------------------------------------------------------------------------------------------

Mold grows on organic foods because the food has not been processed. In the proccessing center, they add many cemicals to keep the food fresher, longer. On organic materials, the food does not last as long (which is why not many food companys choose not to proccess they're food) because the bactiria grow to fast, turning to mold. Then the mold grows faster on the bactiria.

so, basicly it is because the organic food has more (healthy) bactiria.

Answer

Moulds are saprophytes and are specialised to eat dead organic material. The mould spores are airborne and ubiquitous (everywhere). When the mould spore lands somewhere moist it will germinate and if the growing conditions are favourable (i.e. there is a good food source) they will grow and produce a network of hyphea and fruiting bodies which you can see with the naked eye. They can only grow on organic substances as they require a source of carbohydrate because they cannot photosynthesis and are not chemoautotrophs (i.e. they can't make their own energy source). In summary, they grow on organic material because it is their food source.

mold needs moisture, nutrients and a suitable place to grow to conduct. Outdoors, mold can be found on soil, foods, plant matter, and other items. Mold is usally found in wet areas but you should search behind and underneath materials (carpet and pad, wallpaper, vinyl flooring, sink cabinets), furniture, or stored items (especially things placed near outside walls or on cold floors).
