Encyclopedia > Biotic material

Biotic material or biological derived material is any natural material that is originated from living organisms. Most such materials contain carbon and are capable of decay. A natural material is any product or physical matter that comes from plants and animals used to make other objects or products. ...

Examples of biotic materials are wood, linoleum, straw, humus, manure, bark, crude oil, cotton, spider silk, chitin, fibrin, and bone. For other uses, see Wood (disambiguation). ... A linoleum kitchen floor Linoleum is a floor covering made from solidified linseed oil (linoxyn) in combination with wood flour or cork dust over a burlap or canvas backing. ... Bales of straw bundles of rice straw Pile of straw bales, sheltered under a tarpaulin Straw is an agricultural byproduct, the dry stalk of a cereal plant, after the nutrient grain or seed has been removed. ... This article does not cite any references or sources. ... Animal manure is often a mixture of animals feces and bedding straw, as in this example from a stable. ... For other meanings of bark, see Bark (disambiguation). ... Pumpjack pumping an oil well near Sarnia, Ontario Petroleum (from Greek petra – rock and elaion – oil or Latin oleum – oil ) or crude oil is a thick, dark brown or greenish liquid. ... Cotton ready for harvest. ... Spider silk is a fibre secreted by spiders. ... Structure of the chitin molecule, showing two of the N-Acetylglucosamine units that repeat to form long chains in beta-1,4 linkage. ... Fibrin is a protein involved in the clotting of blood. ... This article is about the skeletal organs. ...

The use of biotic materials, and processed biggiuf89iuyotic materials (bio-based material), over synthetics is popular with those who are environmentally conscious because such materials are usually biodegradable, renewable, and the processing is commonly understood and has minimal environmental impact. However, not all biotic materials are environmentally friendly, such as those that require high levels of processing, are harvested unsustainably, or are used to produce carbon emissions. A bio-based material is simply an engineering material made from substances derived from living tissues. ... Top: Increasing atmospheric CO2 levels as measured in the atmosphere and ice cores. ...

When the source of the recently-living material has little importance to the product produced, such as in the production of biofuels, biotic material is simply called biomass. Many fuel sources may have biological sources, and may be divided roughly into fossil fuels, and biofuel. For articles on specific fuels used in vehicles, see Biogas, Bioethanol, Biobutanol, Biodiesel, and Straight vegetable oil. ... See biomass (ecology) for the use of the term in ecology, where it refers to the cumulation of living matter Switchgrass, a tough plant used in the biofuel industry in the United States Rice chaff. ... Fossil fuels are hydrocarbon-containing natural resources such as coal, petroleum and natural gas. ... For articles on specific fuels used in vehicles, see Biogas, Bioethanol, Biobutanol, Biodiesel, and Straight vegetable oil. ...

In soil science, biotic material is often referred to as organic matter. Biotic materials in soil include glomalin, Dopplerite and humic acid. 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 living organism, but contains little organic carbon. Soil science deals with soil as a natural resource on the surface of the earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils per se; and these properties in relation to the use and management of soils. ...

Loess field in Germany Surface-water-gley developed in glacial till, Northern Ireland Technically, soil forms the pedosphere: the interface between the lithosphere (rocky part of the planet) and the biosphere, atmosphere, and hydrosphere. ... This article needs to be wikified. ... Dopplerite is a naturally occurring organic substance found in amorphous, elastic or jelly-like masses, of brownish-black color, in peat beds in Styria and in Switzerland. ... Humic acid is one of the major components of humic substances which are dark brown and major constituents of soil organic matter humus that contributes to soil chemical and physical quality and are also precursors of some fossil fuels. ... An organic compound is any of a large class of chemical compounds whose molecules contain carbon, with exception of carbides, carbonates and carbon oxides. ...

Examples of the use of biotic materials include:
