What are two species types?
Key Stone Species and Invasive Species
Describe Key Stone Species role in their community.
Play in Influential Role, Exert important regulating effect, increase biodiversity
Describe Invasive Species role in their community.
Non-Native, Out compete Native Species, They Lack predators, parasites and competition so they grow rapidly, Reduce Biodiversity
