Question

Why do trees communicate through interconnecting root fungus?

Answer 1

Explanation:

Scientists call these mycorrhizal networks. The fine, hairlike root tips of trees join together with microscopic fungal filaments to form the basic links of the network, which appears to operate as a symbiotic relationship between trees and fungi, or perhaps an economic exchange.

Answer 2

Answer:

The tree then exchanges these offerings from the fungi for a sugar-like substance the tree makes during photosynthesis. ... They do this by sending chemical, hormonal and electrical signals. Not only do they communicate underground, they send pheromones and other scent signals through the air.
