Which statement below best describes how biodiversity contributes to the sustainability of an ecosystem?

• A variety of plant and animal species allows for more survivors of a natural disaster.

• Having more species in an ecosystem allows the human population to increase in size.

• Low biodiversity reduces the competition for resources, which helps native species survive.

• Fewer species in the ecosystem reduces the likelihood that disease spreads through the ecosystem.
