Dirt, or soil, is not abiotic; it is a complex mixture of organic matter, minerals, gases, liquids, and organisms that support life. While the mineral components of soil can be considered abiotic, the organic matter and the organisms (like bacteria and fungi) it contains are biotic. Therefore, dirt is best characterized as a biotic-abiotic system, since it includes both living and non-living components.
