Only one of these three things qualifies as "information" in my book (defence signals). How is this an "information highway"?

[doublerabbit]

Regardless if it's just one piece of information, defence signals; If fungi are connected to a web of plants, trees with communication transversing bi-directionally then it would be very valid to call it an highway of information.

But fungi do more than that. They transfer energy and life resources along the network too. Just as a highway carries cargo.

It's just a metaphor.
