Fungi and trees benefit from each other

But why does fungus transport resources from tree to tree?This is one of the mysteries of the mycorrhizal networks.It makes sense for fungus to exchange soil nutrients and sugar with a tree—both parties benefit.The fungus likely benefits in less obvious ways from being part of a network between trees, but the exact ways aren’t totally clear.Maybe the fungus benefits from having connections with as many different trees as possible,and maximizes its connections by shuttling molecules between trees.Or maybe plants reduce their contributions to fungi if the fungi don’t facilitate exchanges between trees.Whatever the reasons,these fungi pass an incredible amount of information between trees.
