What is one significant impact of climate change on biodiversity?

One significant impact of climate change on biodiversity is the increased extinction risk for vulnerable species. As climate change leads to alterations in temperature, precipitation patterns, and habitat availability, many species, especially those with specialized habitat requirements or limited ranges, become unable to adapt quickly enough to survive these rapid changes.

Habitat destruction from rising sea levels, shifting climatic zones, and more frequent extreme weather events can further threaten species already facing challenges. Species that are already endangered or have small populations are particularly at risk because they often have less genetic diversity and may be less resilient to environmental changes. The loss of biodiversity has far-reaching implications for ecosystems, as each species plays a specific role in its environment, contributing to ecological stability and function.

In contrast, the other choices do not accurately reflect the true impacts of climate change. For instance, decreased levels of carbon dioxide do not occur; in fact, CO2 levels are increasing and contributing to climate change. Ecosystem stabilization is often disrupted rather than promoted by changing climates, and enhanced adaptation rates are not universal or guaranteed for all species. Some species may adapt, but many are likely to face increased mortality or extinction instead.
