Diversity is simply the wide variety of organisms in our world.
Species diversity is a measure that combines the number, or richness, of species and their distribution on land and in the sea. Diversity is the key that unlocks the success of organisms in our world. There are a variety of habitats in our world such as mountains, valleys, deserts, and oceans. Animals and plants that thrive in various habitats each play a unique role. For example, a killer whale plays the role of a top predator in our oceans because of its adaptations for survival, such as its size, powerful swimming, and coloration.
