\nThe correct answer is Abundance of ecological niches.
\n<\/section>\n
\nEcological niches are the roles and positions species occupy within an ecosystem. An abundance of ecological niches means there are many different ways for species to coexist and utilize resources without direct competition, which typically leads to higher biodiversity. Therefore, an abundance of ecological niches is a reason for *high* biodiversity, not low biodiversity.
\n<\/section>\n
\nReasons for low biodiversity include habitat stress (harsh environmental conditions), geographical isolation (limits species migration and gene flow), and dominance by one or a few species (which outcompete or exclude others).
