As long as there are enough producers, an ecosystem is considered to have a good amount of biodiversity.

The rain forest has an unhealthy ecosystem because its biodiversity is too great.

An ecosystem is healthier when the biodiversity is great.

Biodiversity is positively affected when non-native species are introduced into an environment

An invasive species decreased the amount of biodiversity by half

This ecosystem’s deer have increased due the loss of a predator population, now the producer population has decreased by ¼.

This ecosystem suffered a tornado, but due to great biodiversity, it was able to be restored.

This ecosystem is impacted by overfishing, causing 3 fish species to become extinct.

Healthy ecosystems have a stable balance between producer and consumer populations.

Stable ecosystems have more consumers than they can support.
