Soil organisms, such as mycorrhizal fungt impact the rate of succession in ecosystems. Mycorrhizal fungi have a mutualistic relationship with various species of plants and increase the plant growth and survival. Sand dunes often lack mycorrhizal tungl and a researcher wanted to determine the effect of adding mycorrhizal species to sand on disturbed beaches on grass growth.
