A species was added into a particular ecosystem to control the population of a prey species. This method of introducing a new species is called (biological augmentation) , (bioremedation) , or (reforestation). The population of the added species increased, leading to an imbalance in the ecosystem. This increase happened because (the competition for resources increased in the ecosystem) , (the population of prey species increased in the ecosystem) , or (the amount of resources increased in the ecosystem).
