The thin layer where soil and litter meet is especially crucial to this process. This layer of soil is the most biologically active; many species of microarthropods thrive only in the interface between soil and litter.

Microarthropods are important components of the soil decomposer food web. Organic matter is a major influence on microarthropod abundance and diversity. Conservation practices that increase soil organic matter improve soil quality by supporting the development of the soil biotic community. Microarthropods and other small soil animals are visible (sometimes barely so) but miniscule; most require some level of magnification for identification. Many microarthropods, especially springtails and soil mites, are responsible for breaking down organic material into a form that bacteria can consume, and are fundamental to the creation of humus and the formation of soil.

Video 3.Published on Dec 28, 2012Protozoa are a diverse group of unicellular eukaryotic organisms. Protozoa were regarded as the partner group of protists to protophyta, which have plant-like behavior like photosynthesis. Below are some videos showing Protozoan in action. All videos are taken at 400X magnification. Some have flagellum (whip like tales) and others have cilium (hairy edges). As a cysts (can go dormant in bad times), protozoa can survive harsh conditions, such as exposure to extreme temperatures or harmful chemicals, or long periods without access to nutrients, water, or oxygen for a period of time.
Video 4.Published on Dec 28, 2012Bacteria are vital in recycling nutrients, with many steps in nutrient cycles depending on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds such as hydrogen sulphide (H2S)and methane (CH4).
Video 5.Published on Dec 28, 2012The nematodes or roundworms are traditionally regarded as the phylum Nematoda. Nematodes, (small worms) have successfully adapted to nearly every ecosystem from marine to fresh water, to soils, and from the Polar Regions to the tropics, as well as the highest to the lowest of elevations. The oral cavity is lined with cuticle, which is often strengthened with ridges or other structures, and, especially in carnivorous species, may bear a number of teeth. The mouth often includes a sharp stylet, which the animal can thrust into its prey. In some species, the stylet is hollow, and can be used to suck liquids from plants or animals.
