What is one major impact of habitat destruction on wildlife?

• A. Increased access to food sources
• B. Loss of native species and ecosystems
• C. Improved migration patterns
• D. Enhanced biodiversity

Answer: (B)

Habitat destruction is a significant environmental issue that leads to the loss of native species and ecosystems. As natural habitats are altered or eliminated due to factors such as urbanization, deforestation, and agriculture, the plants and animals that rely on these environments for survival are often pushed out or face the threat of extinction. This loss results in a decline in biodiversity, which can destabilize ecosystems and disrupt the complex relationships that exist between species.

When native species are lost, the intricate balance that has developed over time is disturbed, compromising the functioning of the ecosystem. Species may become vulnerable not only due to habitat loss but also because they may not be able to adapt to the faster changes in their environment. This degradation can lead to further consequences such as reduced genetic diversity, which can impede a species' ability to evolve and adapt to new environmental challenges.

In contrast, the other options do not accurately reflect the realities of habitat destruction. Increased access to food sources and improved migration patterns are not typical outcomes of habitat loss, as destruction usually restricts resources and disrupts established pathways. Similarly, enhanced biodiversity would not occur as a direct result of habitat destruction; rather, it typically leads to a decline in biodiversity as native species are lost and ecosystems are compromised.
