Mycorrhizal fungi form symbiotic connections with the roots of most land plants, exchanging soil nutrients for sugars produced by photosynthesis. Underground, these fungal networks can link many trees together, sometimes across species boundaries. Ecologists who study these "wood wide webs" caution that the networks are real and important, but warn against the temptation to project human social metaphors onto fungal biology.
Which choice best states the main idea of the text?
- A
Fungi are more important than plants in forests.
- Bcheck_circle
Mycorrhizal networks genuinely link plants underground, but their workings should not be over-romanticized.
- C
Trees communicate with each other like humans do.
- D
All plants depend on a single fungal species.
Explanation
The passage affirms the networks while warning against overinterpretation — B. A is the metaphor being cautioned against; C and D are unsupported.
