Why Trees Talk to Each Other

Look at a forest. Trees look quiet and still. They stand apart. They seem alone. But underground, a busy world exists. Trees talk to each other every day.

How do trees talk without voices or ears? They use the earth. Under the dirt, a vast network of fungi lives. Fungi are neither plants nor animals. They form long, thin threads called mycelium. These threads connect the roots of different trees. Scientists call this network the "Wood Wide Web."

Through this fungal internet, trees share food. If a young tree grows in a dark place and gets no sunlight, older trees send sugar through the roots. The bigger trees help the baby tree survive.

Trees also share warnings. When insects attack one tree, that tree sends a chemical signal through the roots. Neighboring trees receive the warning. They quickly make bitter chemicals in their leaves. The insects do not like the taste, so they leave. The forest protects itself as a team.

Trees even care for their sick family members. A dying tree often pumps its remaining resources into the network. It gives its nutrients to neighboring trees before it dies.

A forest is not a group of single trees. A forest is one large community. Trees work together to live longer and stronger.
