What is one effect of climate change on biodiversity?

One significant effect of climate change on biodiversity is the increased risk of species extinction. As climate change alters weather patterns and temperatures, many species struggle to adapt to the rapidly changing environment. Habitat loss, changes in food availability, and the spread of diseases and invasive species are all linked to climate-related changes, which can push vulnerable species beyond their limits of survival.

For instance, species that are already at risk, due to factors such as limited range or specialized habitat requirements, face even greater challenges in a warmer world. This heightened vulnerability can lead to population declines and, ultimately, extinction if species cannot migrate to more suitable environments or adapt quickly enough. Climate change fundamentally disrupts the balance ecosystems rely on, contributing to this increased risk of extinction, particularly among species that lack resilience to environmental changes.

In contrast, the other options imply positive outcomes or stability, which are generally not accurate in the context of climate change's impact on biodiversity. For example, while some species may find new habitats as conditions change, this does not translate to a broad expansion of suitable habitats for all species, as many face diminishing ranges. Similarly, ecosystems do not become more stable; rather, they become increasingly fragile as interspecies relationships and environmental conditions are disrupted. Lastly, competition for resources
