To assess the impact of invasive species on ecosystems in Africa, Benis N. Egoh and colleagues reviewed government reports from those nations about how invasive species are undermining ecosystem services (aspects of the ecosystem on which residents depend). The services were sorted into three categories: provisioning (material resources from the ecosystem), regulating (natural processes such as cleaning the air or water), and cultural (nonmaterial benefits of ecosystems). Egoh and her team assert that countries in each region reported effects on provisioning services and that provisioning services represent the majority of the reported services.
Which choice best describes data from the table that support Egoh and colleagues’ assertion?
ExplanationShow
Choice B is the best answer. The finding that all the regions reported at least some effects on provisioning services supports the first part of the assertion. And the fact that provisioning services comprise 75% of the reported services overall supports the second part of the assertion.
Choice A is incorrect. This choice doesn’t fully support the assertion. It doesn’t include the finding that all the regions (not just Central and West) reported at least some effects on provisioning services. Choice C is incorrect. This choice doesn’t fully support the assertion. It doesn’t demonstrate that provisioning services represent the majority of the reported services overall. Choice D is incorrect. This choice doesn’t fully support the assertion. It doesn’t demonstrate that provisioning services represent the majority of the reported services overall.
