Biodiversity Lesson

____________ is the variety of living things in the world.

How do biodiversity and stability work together?

• The lower the biodiversity the greater the stability of an ecosystem.

• The higher the biodiversity, the less stable the ecosystem

• The higher the biodiversity, the greater the stability of the ecosystem.

• Biodiversity has nothing to do with ecosystem stability.
