InterNACHI Mold Inspection Practice Exam

The assertion that mold grows instantly if adequate nutrients are available is partially accurate, but it oversimplifies the complexity of mold growth. Mold does require certain nutrients—such as sugar, starches, and cellulose—to thrive, as these are essential for its metabolic processes. However, the presence of nutrients alone doesn’t guarantee instantaneous growth.

Mold growth also depends on several other environmental conditions, such as moisture levels, temperature, and the presence of suitable surfaces for colonization. While nutrients are a critical factor, they work in conjunction with these other elements. If these additional conditions aren't met (like favorable humidity and warmth), even if nutrients are available, mold may not grow effectively.

For a more accurate understanding, it is essential to recognize that while adequate nutrients can promote mold growth, they are just one piece of the puzzle. The most truthful statement would acknowledge that mold needs nutrients, but it also requires specific environmental conditions to grow rapidly.
