An ecosystem with higher biodiversity is often better able to support life. When an ecosystem has many different species, it can provide more types of food, shelter, and other resources for the organisms living there.
Having many species may also increase an ecosystem's resilience, or ability to handle stress or damage. If one species is wiped out by a disaster or disease, another species may be able to fill the same role in the ecosystem. For example, a disease could wipe out a species that is eaten by many predators. An ecosystem with higher biodiversity is more likely to have other species that those predators can eat.
