The population of an introduced species might increase rapidly due to the absence of natural predators or competitors in the new environment, allowing the species to thrive without the usual checks on its population growth. Additionally, if the introduced species finds ample food resources and suitable habitats, it can reproduce quickly, leading to exponential population growth. Furthermore, successful adaptation to the new environment can enhance survival rates and reproductive success.
Invasive species
When a predator reduces the number of one species in a habitat, the population of competing species can increase. With less competition for food, water, and shelter, a species can thrive and reproduce more rapidly than when it is being out-competed.
introduced to a new area, spreads rapidly, and displaces native species
Those are invasive species.

Because their new habitat lacks the parasites and predators that control their population "back home."
A new species, when introduced to an ecosystem, will compete with the indigenous species for food and resources. If the new species is predatory, it may also begin preying on the indigenous species, so the native populations will decrease sharply.
An introduced species can benefit a community by adding its genes to the future population but it can also be destructive to a community because it could kill off all rivals or pass on a disease.
Factors contributing to the increase in invasive introduced species and losses in global diversity include habitat destruction, climate change, globalization of trade and transportation, and unintentional introductions from human activities. These factors create opportunities for non-native species to establish and outcompete native species, leading to biodiversity loss and ecosystem disruptions.

When exotic species are introduced into an ecosystem they may not have natural predators available. This means that the species will grow rapidly without predation and will stifle other natural species in the ecosystem. An example of this would be zebra mussels in land locked lakes. The mussels were transported by boats and they don't have any predators in the lakes. Their population keeps increasing and they are using all the resources but have nothing to control the population. All the other organisms in the system are then negatively impacted.
It's an introduced species such as rabbits being introduced into Australia.
