TED-Ed: The secret language of trees - Camille Defrenne and Suzanne Simard

The video explores the complex interactions within forest ecosystems, focusing on the role of mycorrhizal networks. These networks, formed by symbiotic fungi, connect tree roots and facilitate the exchange of resources and information. Sugars produced by photosynthesis in tree leaves travel through the tree to the roots, where they are shared with fungi. In return, fungi provide nutrients from the soil. The video also discusses the mysterious reasons fungi transport resources between trees and how these networks enable trees to communicate about environmental threats, ensuring forest health.
