Fine fungal threads can extend the reach of a tree's roots

Mycorrhizal fungi join closely with tree roots and spread thin threads through the soil. The fungi help gather water and minerals, while the tree supplies them with sugars.

The roots bring sugar; the threads bring a wider patch of forest.
