Read the following excerpt from a passage regarding forest ecology.
Recent popular accounts of forest ecology have been captivated by the "Wood Wide Web"—the vast subterranean networks of mycorrhizal fungi connecting tree roots. According to this cooperative model, trees use these fungal pathways to altruistically share carbon and nutrients with stressed neighbors, functioning collectively as a harmonious, egalitarian community. However, a growing faction of evolutionary biologists strongly objects to this narrative. They argue that the mechanics of natural selection preclude genuine altruism between competing plants. Instead, these biologists contend that any resource transfer is merely a byproduct of fungal self-interest; fungi move nutrients from areas of abundance to areas of scarcity simply to maximize their own sprawling biomass, treating trees as interchangeable resource nodes in a strictly transactional framework.
While these critics are entirely correct to banish anthropomorphic notions of tree altruism from ecological science, their reductionist framework overlooks a crucial emergent property of these networks. By focusing exclusively on the evolutionary motives of individual organisms, the biologists fail to recognize that the fungal drive for network expansion inadvertently creates systemic forest resilience. Even if the fungi are merely optimizing their own nutrient portfolios, the resulting redistribution buffers the entire forest against localized droughts and diseases. Thus, we need not invoke cooperative intent to acknowledge that mycorrhizal networks fundamentally operate as decentralized support structures for the ecosystem.
Which one of the following most accurately describes the author’s perspective on the evolutionary biologists' critique of the cooperative model?
- AIt rightly dismisses anthropomorphic interpretations of plant behavior but falsely assumes that fungi act without their own evolutionary motives.
- BIt is fundamentally flawed because it refuses to acknowledge the empirical evidence demonstrating intentional resource sharing among trees.
- It correctly identifies the self-interested mechanisms driving nutrient transfer but is too narrowly focused to appreciate the resulting ecosystem-wide benefits.Answer
- DIt provides a scientifically rigorous and comprehensive account of how source-sink dynamics regulate the distribution of forest resources.
- EIt correctly emphasizes the systemic resilience of forests but fails to attribute this resilience to the transactional behavior of fungi.
