Did you know that trees can communicate with each other? Scientists have discovered something amazing about forests. Under the ground, tree roots are connected by a network of tiny fungi (真菌).
Through this network, trees can share food and water with each other. Older, bigger trees — sometimes called "mother trees" — help younger ones grow by sending them extra nutrients. When a tree is attacked by insects, it can even send warning signals to its neighbours so they can prepare to defend themselves.
This means that a forest is not just a group of trees standing alone. It is more like a big family where everyone helps each other. Next time you walk in a forest, remember — there is a hidden conversation happening right under your feet!
