What could be a direct consequence of removing a top predator from an ecosystem?

Only a few European rabbits (Oryctolagus cuniculus) were released into the Australian wilderness in the 19th century, but they quickly became a huge ecological problem. The rabbits competed with local herbivores and caused native populations to decline along with much of the plant life. The rabbits were so successful in Australia because they-

• 
  lacked natural predators in the environment

• altered their genomes to be more fit

• became predators of other herbivores

• were able to breed with other species

Why are keystone species important for biodiversity?

• They are the most numerous species in their ecosystems.

• They provide food for all other species.

• They help to maintain the structure and integrity of the ecosystem.

• They have no predators, ensuring their survival.
