Scientists have discovered that trees have an underground network that allows them to share information and resources. This amazing system is often called the "Wood Wide Web." Through this network, trees can send warnings about insect attacks. When one tree is attacked by pests, it releases chemicals into the network. Other trees receive this warning and start producing chemicals to protect themselves. This shows that trees are not solitary creatures; they are part of a complex community. Mother trees, the oldest and largest trees in a forest, play a special role. They connect with younger trees through the network and send them nutrients（养分） when they are in need. In this way, mother trees help the young ones survive in difficult conditions. This is similar to how parents take care of their children. However, human activities like deforestation and pollution are damaging this important network. When we cut down trees, we are not just removing individual trees; we are breaking the communication system of the whole forest. This has serious consequences for the health of the ecosystem. Understanding how trees communicate reminds us that nature is more interconnected than we once thought. Every tree, every plant, and every animal plays a part in the web of life. Protecting forests means protecting these delicate connections that keep our planet healthy. 16. What is the "Wood Wide Web"?（不超过10个词） ____________________________________________________ 17.
