Which issue best describes a threat to biodiversity in Forestland?

• A. Introduction of foreign species which damage biodiversity
• B. Construction of shelter
• C. Rapid latrine construction
• D. Floating plastic

Answer: (A)

Introducing foreign species in Forestland threatens biodiversity because invasive species can quickly establish, spread, and disrupt the tightly balanced interactions that living things rely on in a forest. They often outcompete natives for light, water, and nutrients, reducing native plant diversity and altering the structure of the forest understory. They can also prey on native species, introduce new diseases, or bring pests that native species haven’t evolved defenses against. These changes can cascade through the ecosystem, affecting pollinators, herbivores, and predators, and ultimately lowering overall biodiversity and ecosystem function. The other options describe disturbances that can impact forests, but they don’t consistently drive biodiversity loss on the same broad scale. Building shelter or rapid latrine construction can harm local habitat quality and water quality, yet these are situation-specific disturbances rather than widespread drivers of species diversity loss. Floating plastic is a pollution issue most closely tied to aquatic or shoreline environments; while it can affect wildlife, its threat to forest biodiversity is indirect and not as central as the impact of invasive species in altering forest communities.
