There is a strong relation between biome ans species. Of course biome provide the species its habitat, their place to live. The species that live there interact with each other species and make the biome more active and more interesting.
Take for example coral reef biome and sea anemone. The coral reef provide a habitat for the sea anemone. The sea anemone that has a habitat will stayed there for its entire life and decorate the coral reef biome. More fishes were atracted by the anemone and moved there to the coral reef biome. The coral biome will be more active and more interesting place.
