Answer:
The correct answer is: mycorrhizal.
Step-by-step explanation:
Some fungi are fundamental to the health of trees and forests, the mycorrhizal is an example of this.
Mycorrhizal refers to the symbiotic association (the biological relationship between two or more species) of a plant and a fungus.
Mycorrhizal grows on the roots of plants and helps in their nutrition by taking up carbon from their hosts and providing soil nutrients to the plants.
