Mycorrhizae are symbiotic relationships between the roots of plants and fungi that act as extensions of the root system. The fungi supply the plant with certain nutrients, and the plant in turn supplies the fungi with carbohydrates.

Symbiotic relationships are usually referred to as "give and take" but this is not always the case, whilst some may be beneficial eg. mutalistic, commensalistic others are not eg. parasitism. The isopod falls into the parasitic category where one species benefits and the other does not.
