One suitable definition of organic matter is biological material in the process of decaying or decomposing such as humus. Organic wastes including faeces and dead tissues. As previously mentioned saprophyte is an umbrella term that is used to describe a variety of species of organisms that feed on decaying and dead organic material plant material.

Organic matter could mean a lot of things. On farms the main sources of organic matter are plant litter plant roots stubble leaves mulch and animal manures. Active carbon is very important to a healthy soil.

Technically detritivores are organisms that have to ingestconsume dead matter to process it while decomposers may be able to absorb the nutrients and break down the organic material without ingesting it. Also some worms. Saprophyte Next answer below I agree the term saprophyte or saprotroph would be used for fungi which digest the dead leaves or animal matter saprotrophically.

Mold is often used interchangeably with the word mildew. Aggregate The term scientists use to describe the clumps of organic and inorganic matter that make up soil. Ammonia is a compound made from the elements nitrogen and hydrogen.

It also supplies food for the microbial population. The fresh residues or dead organic matter consist of recently deceased microorganisms insects earthworms old plant roots crop residues and recently added manures. 76 Humus comes mostly from dead microorganisms and plants.

Natural organic matter NOM is the generic term for a mixture of organic slightly water-soluble components. It includes living plant roots and animals plant and animal remains at various stages of decomposition and microorganisms and their excretions. The dead is what we call the active carbon pool.

A Humus B Loam C Pyrite D Xenocompost. _____ is the term used to describe the very slow movement of soil loose-sediment and weathered rock. Decomposition is a general term used to describe the interrelated processes by which organic matter is broken down to CO 2 and humus with a simultaneous release of nutrients.

DXenocompost 2Which of the following is NOT a degradation product of organic material. 19 Mercury has both organic and inorganic forms that are neurotoxic. 22 Mercury can serve as a transcriptional activator.

This pool is where nutrient and aggregate glues are found. In some cases just looking at them is enough to identify the origin of the fresh residues Figure 22. 1_____ is a term used to describe dead organic matter.

12 The most general route for NOM in soil sediments and natural waters are humic substances that contribute to the brownish-yellowish color of natural waters. Chapter 20 Nutrient Cycles Multiple Choice 1 _____ is a term used to describe dead organic matter. Due to the chemical complexity of these organisms humus itself contains very diverse chemicals.

Ammonia A colorless gas with a nasty smell. Detritus is a Biology term used to describe non-living material in particulate form not dissolved material. Organic matter is any living or dead animal and plant material.

Humus broadly contains fulvic acid humic acid and humin. 21 Some bacteria have genes that confer resistance to mercury. Such as dead leaves.

These are just a few types of saprophytes. It is called humus when the organic matter has broken down into a stable substance View the full answer. Our air soils fresh water and climate are all maintained by natural processes.

The decomposition process often begins with soil macrofauna. Examples of organic compounds present in humus are lignin derivatives and other recalcitrant aromatic compounds. Tilted fence posts curved tree trunks.
