In biology, abiotic components are non-living chemical and physical factors in the environment.[1] Despite being non-living, abiotic components can impact evolution. Things that were once living but now dead are usually considered biotic (for example, corpses and spilled blood). However, depending upon the definition, components from living things that are no longer living can be considered part of the biotic or abiotic component. Generally, things that were once living are considered part of the biotic component, but body waste such as feces, urine (and carbon dioxide, oxygen, and water from respiration) are considered abiotic because those components were never living in an organism.
