Underground Fungal Networks That Connect Ecosystems Trees and plants talk to each other using tiny threads in the soil. These threads are fungi. Scientists call this network "mycorrhizal fungi." The word "mycorrhizal" means "fungus-root." These fungi connect to plant roots and make a big network under the ground. They help plants get water and food from the soil. This fungi network works like the internet for plants. Big trees can send food to small trees through these connections. When one tree is sick, it can send warning signals to other trees. Then other trees make special chemicals to protect themselves. Some scientists call this system the "Wood Wide Web." This is a funny name that sounds like "World Wide Web" for computers. These fungi help about 90% of all land plants. They exist in forests, grasslands, and even gardens. The fungi networks are very old. They have been on Earth for more than 400 million years. They help make the soil good. As a result, plants grow better with these fungi friends. We must protect these fungi networks. When we cut down forests or use too many chemicals, we hurt them. If we care for them, healthy fungi help plants and trees grow strong. The mycorrhizal internet shows us that nature is connected. All living things work together in a big system.
