One technique used to check ecosystem health and biodiversity of an ecosystem is to monitor populations of native species and introduced species. native species are species that were present in an ecosystem before humans began altering it. generally, the more native species that are present, the healthier the ecosystem. introduced species are species that humans bring into an ecosystem from other ecosystems. introduced species can become invasive species if they outcompete native species for local resources. in some cases, invasive species can cause native species to disappear from an ecosystem, or even to become extinct. some invasive species can even become the only species of its kind in an ecosystem, which greatly reduces biodiversity. based on this information, which of the following ecosystems is the healthiest and most diverse?
