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.

The grassland ecosystem is most sustainable because there are fewer organisms that eat grass.
The forest ecosystem is most sustainable because most of the animals can eat other organisms.
