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 ]
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.
Decomposition or rot is the process by which dead organic substances are broken down into simpler organic or inorganic matter such as carbon dioxide, water, simple sugars and mineral salts. The process is a part of the nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.
Organic matter, matter that has come from a once-living organism, or is composed of organic compounds; A chemical substance present or produced in a living organism Biomolecule, a molecule present in a living organism; Biogenic substance, a chemical substance produced by a living organism
Primary production is the production of organic matter from inorganic carbon sources. This mainly occurs through photosynthesis. The energy incorporated through this process supports life on earth, while the carbon makes up much of the organic matter in living and dead biomass, soil carbon and fossil fuels.
Most synthetically-produced organic compounds are ultimately derived from petrochemicals consisting mainly of hydrocarbons, which are themselves formed from the high pressure and temperature degradation of organic matter underground over geological timescales. [2]
And for packaged foods, it’s all about the ingredients: For a food item with multiple ingredients to be considered organic by the USDA, at least 95% of those ingredients have to be certified ...
The degradation rate of many organic compounds is limited by their bioavailability, which is the rate at which a substance is absorbed into a system or made available at the site of physiological activity, [11] as compounds must be released into solution before organisms can degrade them. The rate of biodegradation can be measured in a number ...
