Trees secretly chat using underground fungi

A forest is not just a collection of trees; it is a complex, interconnected system linked by an underground fungal web. Trees use a network of fungi called mycorrhizae to talk to one another and trade supplies.

This fungal thread connects the roots of different species throughout the forest floor. When a tree is attacked by beetles, it sends chemical 'data packets' through the network to warn its neighbors.

In response, the surrounding trees start pumping out toxins to prepare for the invasion before the bugs even arrive. Some studies suggest older trees may transfer nutrients to younger ones, though scientists debate how much of this is directed specifically to their own saplings.

This isn't just a friendly exchange. The fungi can take up to 20% of the tree's sugar in exchange for providing minerals like phosphorus and nitrogen.

If a tree is dying, it can dump its remaining nutrients back into the network to be used by its survivors. It's a literal biological socialist system hidden beneath your feet.

Some orchids have even figured out how to 'hack' the system, plugging into the web to steal nutrients without giving anything back.
