Some species of fungi create elaborate underground networks to share nutrients with surrounding plants, fostering a symbiotic relationship known as mycorrhizal mutualism.
In these fungal 'garden' networks, trees and other plants receive essential nutrients like phosphorus and water, while the fungi receive carbohydrates produced by the plants during photosynthesis. This mutually beneficial relationship can even enhance the plants' resistance to disease and pests, creating a stronger, healthier ecosystem.
