How does identifying ecological hotspots help maintain biodiversity quizlet?
Biodiversity hotspots are important because it is within these unique ecosystems that many rare and endangered species exist. Therefore, it is important to study and protect these areas. As we have learned, the more diverse (in every sense) the ecosystem, the hardier it is.
