Organic Matter
Organic matter, organic material, or natural organic matter refers to the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have come from the feces and remains of organisms such as plants and animals. Organic molecules can also be made by chemical reactions that do not involve life. Basic structures are created from cellulose, tannin, cutin, and lignin, along with other various proteins, lipids, and carbohydrates. Organic matter is very important in the movement of nutrients in the environment and plays a role in water retention on the surface of the planet.
Recent review conceptualizes how soil fauna can alter the stability of carbon in soil via processes such as tranformation/translocation of organic matter or grazing on microorganisms. Better understanding of the quantitative contribution of these processes could aid in managing soils as carbon sinks
