Different kinds of mycorrhizae occur in different ecosystems. For example, as you walk up a mountain, you might find one type of mycorrhizae in lower regions and a second, different type of mycorrhizae in higher regions. Why are there mycorrhizae specific to certain ecosystems

Mycorrhizae are adapted to the type of soil and the type of vegetation present.

Explanation:

Mycorrhizae or 'fungus root' is defined as the mutualistic relationship that occurs between the plants and the fungus. The fungus and plants showing the mutualistic beneficial relationship with each other (such as Ectomycorrhiza show mutual relationships with woody plants, involving pine)

In this relationship, plants provide nutrients to the fungus and where fungus helps in the uptake of nutrients and water to the plants. Mycorrhizae are adapted to the type of soil and the type of vegetation present around the regions.
