to a large extent,is biodiversity

Our planet's diverse thriving ecosystems may seem like permanent fixtures,but they're actually vulnerable to collapse.Jungles can become deserts,and reefs can become lifeless rocks,even without cataclysmic events, like volcanoes and asteroids.What makes one ecosystem strong and another weak in the face of change?The answer, to a large extent,is biodiversity.Biodiversity is built out of three intertwined features:ecosystem diversity,species diversity,and genetic diversity.
