Which of the following best describes the impact of habitat destruction on biodiversity?

Habitat destruction has a profound impact on biodiversity, primarily leading to a decrease in species diversity. When habitats are altered or destroyed, many species lose their homes, food sources, and breeding areas. This loss can result in populations declining or becoming extinct, as organisms that cannot adapt to rapid changes or migrate to new areas may not survive. The reduction in variety of species not only affects those organisms directly impacted by habitat loss but also has a cascade effect on the entire ecosystem, disrupting food chains and ecological relationships.

In contrast to the other options, which suggest positive outcomes such as increased stability, enhanced migration, or promotion of ecological succession, the reality of habitat destruction overwhelmingly aligns with a decline in the number of species that can thrive in affected environments. This makes it critical to understand habitat preservation's role in maintaining biodiversity and ecosystem health.
