Biodiversity Review

How are biodiversity and sustainability related?

• A greater amount of species means ecosystems are more likely to survive changes

• The fewer the species, the greater chance an ecosystem has of surviving

• The greater the biodiversity, the fewer links in the food web to support the ecosystem

• Ecosystems can maintain sustainability without a lot of biodiversity.
