Organic matter (or organic material) is matter which has come from a recently living organism; is capable of decay, or the product of decay; or is composed of organic compounds. The definition of organic matter varies upon the subject it is being used for. In physics, matter is commonly defined as the substance of which physical objects are composed, not counting the contribution of various energy or force-fields, which are not usually considered to be matter per se (though they may contribute to the mass of objects). ...
Benzene An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and elementary carbon. ...
Once living matter Organic matter may refer simply to matter which was once part of a living organism or produced by a living organism. This definition is synonymous with biotic material, and would include a clam's shell and naturally produced urea, while excluding synthetically produced urea. While this definition is useful for modelling nutrient flows, it is not useful in measuring the organic content of soil. Biotic material is any natural material that originated from living organisms. ...
Urea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO. Urea is also known as carbamide, especially in the recommended International Non-proprietary Names (rINN) in use in Europe. ...
Decay Organic matter may be defined as material that is capable of decay, or the product of decay (humus), or both. Usually the matter will be the remains of recently living organisms, and may also include still-living organisms. Polymers and plastics, although they may be organic compounds, are usually not considered organic material, due to their poor ability to decompose. A clam's shell, while biotic, would not be considered organic matter by this definition because of its inability to decay. Humus is a word actually used for two different things, which are both related to soil and thus get used interchangeably. ...

Organic chemistry Measurements of organic matter generally measure only organic compounds or carbon, and so are only an approximation of the level of once-living or decomposed matter. Some definitions of organic matter likewise only consider "organic matter" to refer to only the carbon content, or organic compounds, and do not consider the origins or decomposition of the matter. In this sense, not all organic compounds are created by living organisms, and living organisms do not only leave behind organic material. A clam's shell, for example, while biotic, does not contain much organic carbon, so may not be considered organic matter in this sense. Conversely, urea is one of many organic compounds that can be synthesized without any biological activity. Benzene An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and elementary carbon. ...

Vitalism The equation of "organic" with living organisms comes from the scientifically abandoned idea of vitalism that attributed a special force to life that alone could create organic substances, which was first called into question by the abiotic synthesis of urea by Friedrich Wöhler in 1828. Vitalism is the doctrine that vital forces are active in living organisms, so that life cannot be explained solely by mechanism. ...
Friedrich Wöhler (July 31, 1800 - September 23, 1882) was a German chemist, best-known for his synthesis of urea, but also the first to isolate several of the elements. ...
