WebOther living SOM include nematodes, insects, earthworms, plant roots and small animals. Dead organic matter (about 15%) serve as food for living organisms and include dead microbes, old plant roots, crop residues and bodies of larger insects and animals.. Very dead organic matter (about 70%) are well decomposed, dark colored organic substances … The organic matter in soil derives from plants, animals and microorganisms. In a forest, for example, leaf litter and woody material falls to the forest floor. This is sometimes referred to as organic material. When it decays to the point in which it is no longer recognizable, it is called soil organic matter. When the organic matter has broken down into a stable substance that resist further decomposition it is called humus. Thus soil organic matter comprises all of the organic m… how kindness can be contagious in healthcare
