Question

poets have long praised forests as oases of quiet, but research reveals that plants and fungi may be louder than we realize—at least, they are when theyre speaking to each other. at the center of this conversation are mycorrhizal fungi, a type of fungus that has complex networks of root - like mycelia linking each fungus to the surrounding trees. vital to the forests health, this wood wide web shares resources amongst plants and fungi that need them most. for example, mycorrhizal fungi share hard - to - access resources like nitrogen with local trees. in return, the trees send sugars back to the fungi. and certain trees with more access to resources like sunlight will even use mycelia to send care packages to trees with less access to resources. and this underground network is useful for more than just food - sharing; researchers have determined that trees also use it to share important messages. for instance, trees attacked by harmful insects will send chemical warnings through the mycelia. trees connected to the network will release compounds meant to drive off pests. how do mycelia contribute to the health of forests? choose 1 answer: a mycelia serve as the root system for mycorrhizal fungi, enabling them to ensure that all plants have perfectly equal access to needed resources. b mycelia are the chemicals that trees release to drive off harmful pests, allowing the forest to protect its most vulnerable species from damage. c mycelia allow trees to send off warning messages, and also directly drive off harmful pests themselves. d mycelia allow plants and fungi to share resources, and also enable plants to better protect themselves through a shared warning system.

Explanation:

The text states that mycelia form a "Wood Wide Web" that shares resources among plants and fungi. Also, trees use mycelia to send chemical warnings. Option D summarizes these functions correctly. Option A is wrong as it mentions "perfectly equal access" which is not stated. Option B misidentifies mycelia as chemicals. Option C says mycelia directly drive off pests which is incorrect - trees release compounds for that.

Answer:

D. Mycelia allow plants and fungi to share resources, and also enable plants to better protect themselves through a shared warning system.
