The addition of the rabbits to this established ecosystem caused many problems, including a huge decrease in native plants. This left little food for native animals. This is an example of how
Adiversity improves an established ecosystem.
Bgenetic variation leads to the formation of a new species.
Cthe introduction of non-native species upsets a balanced system.
Dchanging in one part of a system does not affect other parts of the system.
