How do fungi in the soil of rain forests encourage plant diversity? a. by serving as pathogens for particular plant species, fungi encourage plant diversity b. by serving as pollinators, fungi introduce plant diversity into new regions c. by forming mycorrizhae with plants, fungi introduce plant diversity into new regions

Option-C

Explanation:

The organisms of the Fungi form the symbiotic relationship with the plants by living in their roots. This symbiotic relationship is known as the mycorrhizal association which provide phosphorus to the plant.

The research on the correlation between the fungal species and plant diversity shows that the fungal species help increase diversity. The fungi form the hyphae structures which connect one plant with another plant and increases their communication level and distribute the phosphorus nutrients in the plants. This help increases the diversity of the plants.

Thus, Option-C is correct.
