Sentences with phrase «microbial activity»
Microbial activity refers to the actions and behaviors of tiny living organisms called microbes. These microbes, which include bacteria, fungi, and viruses, carry out various tasks such as breaking down organic matter, converting nutrients in soil, producing energy, and causing diseases. So, microbial activity basically describes the actions performed by these extremely small organisms. Full definition
