Florida Biology EOC Practice Test

Which of the following actions can reduce biodiversity?

1. Climate changes

2. Immigration

3. Introduction of native species

4. Transpiration

The correct answer is: Climate changes

Biodiversity refers to the variety and variability of life within an ecosystem. A diverse ecosystem is generally more resilient, meaning it is better able to withstand changes and disturbances. Climate change and the associated changes in temperature, precipitation, and other environmental factors can have a significant impact on biodiversity. It can cause certain species to go extinct, disrupt the natural balances in the ecosystem, and ultimately reduce overall diversity. Therefore, climate changes can reduce biodiversity. Immigration, or the movement of individuals into an established population, can actually increase biodiversity. This is because it introduces new genetic variation and potentially new species into the ecosystem. The introduction of native species, while potentially disrupting the existing ecosystem, generally does not reduce biodiversity. This is because native species are already part of the natural balance and do not significantly alter the existing biodiversity. Transpiration, the process by which plants release water vapor into the atmosphere, does not directly impact biodiversity. It is a natural and essential process for plants to survive and is not inherently harmful to biodiversity. Therefore, it is not a correct answer to the question.
