Nematode trapping fungi
Introduction
Nematode trapping fungi, or “nematophageous fungi,” are carnivorous fungi that have developed methods and structures that enable them to successfully trap and consume nematodes. Nematode trapping fungi are responsible for keeping the nematode population in check and are an important part of the subsoil ecosystem. These fungi prey on nematodes and are in turn consumed by organisms on the next trophic level. Nematophageous fungi use several methods to hunt their prey. These methods include living within the nematode and slowly consuming them as well as spreading diseases through nematode populations. The fungi also live in the soil and set traps for the nematodes to squirm into.
Biological interaction
Nematophageous fungi and nematodes share a special predator-prey relationship. Nematodes produce a highly conserved family of small molecules called ascarosides. These small molecules are special to the nematodes and the fungi are able to detect these molecules. Studies have shown however, that these molecules are only being detected during periods of nutrient scarcity on the part of the fungi.

Key Microorganisms
What specific kinds of microbes are typically involved in this interaction? Or associated with important processes?
