Which action could negatively impact biodiversity in Forestland?

• A. Introducing foreign species
• B. Expanding crop selection
• C. Tree planting
• D. Education

Answer: (A)

Introducing foreign species can negatively impact biodiversity because non-native species can become invasive, spreading rapidly and outcompeting native plants for light, water, and nutrients. When natives are displaced, the whole ecosystem—food webs, pollination networks, and habitat structure—can shift or collapse, leading to fewer species and less resilience to disturbances. They may also bring new diseases or parasites to which native species have little resistance, further threatening local biodiversity and ecosystem services. The other options are generally more compatible with sustaining biodiversity. Tree planting, especially with a mix of native species, adds habitat and resources for forest wildlife. Education promotes practices that protect habitats and species. Expanding crop selection can alter land use, but it doesn’t inherently trigger the widespread, rapid ecological disruption caused by invasive species.
