"Biogenic" refers to substances or materials that originate from living organisms. This term is often used in fields like biology, ecology, and geology to describe processes or products that are the result of biological activity. For example, biogenic minerals are formed through the actions of organisms, such as the shells created by marine life. In addition, biogenic compounds can include organic matter produced by plants and animals, which play a crucial role in ecosystems. These compounds contribute to soil fertility and are essential for nutrient cycling. Understanding biogenic processes helps scientists study environmental changes and the impact of living organisms on their surroundings.
