Which environmental condition does not favor the growth of non-decay fungi?

Low humidity is the condition that does not favor the growth of non-decay fungi. Fungi generally thrive in environments where moisture is abundant, as they require water for their metabolic processes and reproduction. Low humidity indicates a dry environment, which limits the availability of moisture needed by fungi to germinate, grow, and proliferate.

In contrast, excessive moisture, high temperatures, and stagnant air contribute positively to fungal growth. Excessive moisture provides the necessary water that fungi need. High temperatures can enhance metabolic rates and spur growth by facilitating biochemical reactions essential for their development. Stagnant air can also maintain humidity levels, preventing moisture from evaporating and creating an environment conducive to fungal colonization. Therefore, low humidity stands out as an unfavorable condition for non-decay fungi.
