What term refers to microscopic organisms that live off organic material and cause decay?

Explanation:
Fungi. They are microorganisms that feed on organic material and drive decay by releasing enzymes that break down complex substances into absorbable nutrients. This decomposing activity is a hallmark of fungi and explains why damp, nutrient-rich environments promote mold and yeast growth. In healthcare contexts, understanding fungi helps with moisture control and infection prevention, since some fungi can cause infections in susceptible individuals. The other options are not living microorganisms: hazardous waste is a waste category, health care is a setting, and full containment is a containment level.
