Which of the following is not a possibility for increased temperatures and rainfall affecting biodiversity?

Increased temperatures and rainfall can impact biodiversity in several ways, but the assertion that higher temperatures and rainfall would lead to increased genetic diversity is not necessarily true. Genetic diversity within a species is often influenced by various factors, including population size, mating patterns, and environmental pressures.

When species experience stress due to changing climates, they may not have the ability to adapt quickly enough to survive, leading to declines in certain populations rather than increases in genetic diversity. Adaptation typically requires a stable genetic pool to select from, and rapid environmental changes can reduce the size of populations, leading to a loss of genetic variation.

Conversely, the correct options illustrate outcomes that are more likely to occur as a direct result of climate change. Species may adapt to their changing environment over time, but this adaptation often requires a gradual process. Additionally, reduction of habitat can happen as some environments become inhospitable due to climate shifts, which can threaten the survival of species. Increased competition for resources is another likely outcome, as species may struggle to find adequate food and space in a changing landscape, putting pressure on their populations.

Thus, while adaptation, habitat reduction, and competition are realistic responses to climate change, increased genetic diversity in the face of such challenges is not a
