Impact of Exotic Species

What is the impact of exotic species introduced into the ecosystem?

Page 2: Exotic Spp

As ecosystems evolve and become more diverse and more stable, the organisms within the ecosystem achieve a dynamic balance.

Each is connected and dependent on the others.

Page 3: Exotic Spp

Environmental resistance and each organism’s biotic potential interact to keep the populations balanced.

If the interaction between indigenous (native) species is lost, the balance is upset and the web of connections begins to unravel.

Page 4: Exotic Spp

The introduction of exotic (non-indigenous) species can upset the balance.

What are some examples of exotic (non-indigenous) species?
