What is a key characteristic of molds as non-pathogenic fungi?

1. They are always harmful.

2. They thrive in dry environments.

3. They can benefit soil health.

4. They produce antibiotics.

The correct answer is: They can benefit soil health.

Molds, as non-pathogenic fungi, play a crucial role in benefiting soil health. They contribute to the decomposition of organic materials, aiding in nutrient cycling and improving soil structure. This process enriches the soil, making it more fertile and capable of supporting plant life. The presence of molds in the soil enhances its microbial diversity, promoting a healthy ecosystem. The other options do not accurately represent the characteristics of molds. For instance, the notion that molds are always harmful is incorrect, as many molds are non-pathogenic and beneficial for ecological processes. Additionally, molds typically thrive in moist environments rather than dry ones, which is contrary to the suggestion of thriving in dry conditions. While some molds can produce antibiotics, this is not a defining characteristic for all molds and not their primary role in the environment. Therefore, recognizing their beneficial impact on soil health highlights an essential aspect of molds as non-pathogenic fungi.
