Although the concept of the "Wood Wide Web" popularized the idea that trees in a forest cooperatively share nutrients through underground fungal networks, recent studies suggest a more complex reality. Researchers who tracked isotope movement between tree roots found that while carbon and nitrogen do move between plants via these mycorrhizal associations, the transfer is rarely a unilateral act of altruism. Instead, the fungi themselves actively regulate the flow to maximize their own survival, often retaining resources or distributing them in ways that exploit the trees' resource deficits. Thus, what was once viewed as a cooperative superorganism is better understood as a network of tense, transactional negotiations between distinct species.
Which choice best states the main idea of the text?
- Rather than facilitating purely cooperative resource sharing among trees, underground fungal networks act as self-serving mediators in a transactional exchange.Cevap
- BFungal networks are the primary mechanism driving all biological and ecological interactions within forest ecosystems.
- CRecent research shows that fungi distribute nutrients to trees solely to prevent trees from experiencing resource deficits.
- DThe competitive nature of mycorrhizal networks will eventually lead to the collapse of forest ecosystems.
