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 . [ 1 ]
Rammed earth is more often considered for use in walls, although it can also be used for floors. Rammed earth and caliche block can be used for structural walls, and offer great potential as low-cost material alternatives with low embodied energy. In addition, such materials are fireproof. Caliche block and rammed earth can be produced on-site.
The branch of chemistry that studies organic compounds is known as organic chemistry. [ 15 ] Carbon is the 15th most abundant element in the Earth's crust , and the fourth most abundant element in the universe by mass, after hydrogen , helium , and oxygen .
Some biotic material may not be considered to be organic matter if it is low in organic compounds, such as a clam's shell, which is an essential component of the exoskeleton of bivalve mollusks made of calcium carbonate (CaCO 3), but contains little organic carbon.
Strange matter: A type of quark matter that may exist inside some neutron stars close to the Tolman–Oppenheimer–Volkoff limit (approximately 2–3 solar masses). May be stable at lower energy states once formed. Quark matter: Hypothetical phases of matter whose degrees of freedom include quarks and gluons Color-glass condensate
Other compounds and materials that are considered 'inorganic' by most authorities include: metal carbonates, simple oxides of carbon (CO, CO 2, and arguably, C 3 O 2), the allotropes of carbon, cyanide derivatives not containing an organic residue (e.g., KCN, (CN) 2, BrCN, cyanate anion OCN −, etc.), and heavier analogs thereof (e.g ...
Peat is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands , bogs , mires , moors , or muskegs . [ 1 ] [ 2 ] Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute.
The organic matter is usually a component of sedimentary material even if it is present in low abundance (usually lower than 1%). Petroleum (or oil) and natural gas are particular examples of sedimentary organic matter. Coals and bitumen shales are examples of sedimentary rocks rich in sedimentary organic matter.
