Which choice below best describes the factors that can affect an ecosystem's stability?

Biotic and abiotic factors.

Predator and prey relationships.

Organic and inorganic materials.

Autotrophic and heterotrophic organisms.

Predator and Prey relationships would have the most effect on an ecosystem's stability because they keep a limit number on the opposing population (ex. rabbit population can only get so high because wolves keep eating them / wolf population can only be so high because there is't enough rabbit to eat)
