What biological material supports mold growth effectively?

Mold thrives in environments that provide biological material, which serves as a food source for its growth and reproduction. Organic materials, such as wood and paper, contain cellulose and other nutrients that molds can readily digest. This makes these types of materials particularly conducive to mold growth.

In contrast, synthetic materials like plastic do not contain organic nutrients necessary for mold to flourish. Metals and glass are also unsuitable for mold growth since they lack the essential organic compounds that support mold nutrition. Processed materials like cardboard may have some organic components, but they are not as nutrient-rich as pure organic materials like wood and paper. Hence, while the processed materials can support mold to a limited extent, they do not compare to the effectiveness of genuine organic materials in promoting optimal mold growth.
