The Question: In a healthy forest, trees are said to ‘communicate’ with each other via…
C Electrical currents
Below the surface of a healthy forest is a vast network of fungus called mycelium. It’s made up of microscopic ‘threads’ that wrap around or bore into tree roots, connecting the trees through a ‘mycorrhizal network.’ Through this network, individual trees (and other plants) can transfer water, nitrogen, carbon, and other minerals to each other. For example, seedlings like this one growing in a particularly shady area won’t receive enough sunlight to perform adequate photosynthesis. To survive, the seedling relies on nutrients and sugar from older, taller trees sent through the mycorrhizal network. This complex interconnectedness has earned the mycorrhizal network a nickname: the Wood Wide Web.
The correct answer is Fungus.
