Unit 2 The Living World: Biodiversity

If an island is closer to the mainland, how will this impact the biodiversity?

• There will be a higher level of biodiversity here than an island that is further away.

• There will be a lower level of biodiversity here than an island that is further away.

• There will be no difference in biodiversity on islands based on distance to mainland.
