Imagine a foreign mountain lion species is introduced into the ecosystem. How would this affect the other organisms?

mixas84 [53]

Depending on the ecosystem, various things could happen. For example, if you introduced it to a forest/mountain area (Northern USA) a large cycle would change. Within 15 years, the mountain lions would prey on deer, mice and rabbits. The decrease in those populations would lead to an increase in plant wildlife. The variety in new plants could bring new animals like wild bison or even beavers.

Hope this helped.
