While researching mycorrhizal networks, a student takes the following notes:
* Mycorrhizal networks are underground webs formed by fungi that connect the roots of neighboring plants.
* These networks allow plants to share nutrients, water, and chemical warning signals.
* In 1997, ecologist Suzanne Simard conducted a landmark study on Douglas fir and paper birch trees in British Columbia.
* The study tracked the movement of carbon isotopes and showed that Douglas firs transferred carbon to paper birches via fungal links.
* Simard's research provided the first concrete field evidence of interspecies resource sharing through mycorrhizal networks.
The student wants to summarize the landmark study and its findings. Which choice most effectively uses information from the given notes to accomplish this goal?
- AMycorrhizal networks are underground webs formed by fungi that connect the roots of neighboring plants, facilitating the transfer of essential nutrients, water, and chemical warning signals.
- BIn her 1997 study of British Columbia forests, ecologist Suzanne Simard proved that paper birch trees must rely entirely on Douglas firs for carbon transfer because their root systems are not connected to mycorrhizal networks.
- In a landmark 1997 study, ecologist Suzanne Simard demonstrated that Douglas fir trees transfer carbon to paper birch trees, providing the first field evidence of resource sharing between different species via mycorrhizal networks.Cevap
- DEcologist Suzanne Simard's landmark 1997 study of Douglas fir and paper birch trees demonstrates that all plant species in forest ecosystems survive primarily by sharing carbon through underground networks.
