organic matter is matter composed of organic compounds that has come from the remains of organisms such as plants and animals and their waste products in the environment
Plants...
Loam is good for growing plants because there are a lot of minerals.hThere is decay in loam.That helps plants grow too.Very many organic matters from the mixture of moist clay soil is good for planting.
Nitrogen-fixating prokaryotes (such as bacteria) present in the roots of legumes and some other plants take N2 from the air and convert it to nitrogen compounds usable by plants. Nitrogen fixing bacteria (diazotrophs).
oil
Peat is derived from partially decayed plants and other organic material. It is made from living and formerly living things. The main use of peat is as a fuel source.
The main source of organic matter in soil is decomposed material from dead plants, animals and the solid waste resulting from animal digestion. Insects and bacteria act on them breaking them down into smaller and smaller pieces that mix with the rest of the soil.

The source of the energy plants use to make carbohydrates is the Sun. Through the process of photosynthesis, plants capture sunlight and convert it into chemical energy stored in the form of carbohydrates. Bacteria and organic matter play important roles in the decomposition and nutrient cycling processes in ecosystems, but they are not the direct source of energy for carbohydrate synthesis in plants. Groundwater does not directly contribute to the energy production in plants.
organic matter in it
Some Bacteria fix nitrogen from the air and give it to plants, others degrade complex organic compound into inorganic elements which are taken by the plants; in return plants synthesize organic compounds used by bacteria for energy. Bacteria associated with plants to fix nitrogen and benefited by the plants for space and energy are called symbiotic bacteria.
Biomass
Atmospheric carbon dioxide is the main source of carbon. Green plants store this carbon during the process of photosynthesis. Carbon dioxide supplies the carbon needed for all the organic matter.
Photoautotrophs: Bacteria that use sunlight as their energy source and carbon dioxide (as part of photosynthesis) as their carbon source. These bacteria thus obtain all their nourishment through photosynthesis Photoheterotrophs: Bacteria that use sunlight as their energy source and organic compounds from the environment as their carbon source.
Biomass is considered a renewable resource because the energy source will come from organic matter such as garbage or crop waste.
It is refined from organic material. A source would be bacteria acting on milk.
Carbon is what humus is a source of.Specifically, the term designates organic matter in soil. The organic matter is created by the decomposition of animal and plant matter. Decomposition results in increased availability of carbon. Humus also will attract ammonium, copper, magnesium, potassium and zinc.
