Microfauna are present in every habitat on Earth. They fill essential roles as decomposers and food sources for lower trophic levels, and are necessary to drive processes within larger organisms. Populations of microfauna can reach up to ~10 (~10,000,000) individuals per g (0.1g, or 1/10th of a gram)
95:
Microfauna also inhabit freshwater ecosystems. For example, freshwater microfauna in
Australia include rotifers, ostracods, copepods, and cladocerans. Rotifers are filter feeders that are usually found in fresh water and water films. They consume a variety of things including bacteria, algae, plant

and are very common in plant litter, surface soils, and water films. Many microfauna, such as nematodes, inhabit soil habitats. Plant parasitic nematodes inhabit the roots of various plants, while free-living nematodes live in soil water films.

Soil microfauna are capable of digesting just about any organic substance and some inorganic substances. These organisms are often essential links in the food chain between primary producers and larger species. For example,
