Trees communicate through underground fungal networks.

Trees have a fascinating way of communicating with each other through a symbiotic relationship with fungi in the soil. These underground networks, known as mycorrhizal networks, allow trees to send chemical signals and share nutrients with each other. Through this system, trees can support each other, send warnings about threats such as insect infestations, and even transfer resources to those in need. This intricate network highlights the interconnectedness of forests and the complex ways in which trees support each other's survival and growth.
