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.

When the population of a species begins declining rapidly, the species is said to be endangered or at risk of extinction. This status indicates that the species faces a high likelihood of becoming extinct in the near future if the threats to its survival are not addressed. Conservation efforts are often implemented to protect and recover endangered 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.
Exponential growth of a newly introduced species may occur initially due to abundant resources and a lack of natural predators, allowing the population to expand rapidly. However, this growth is often short-lived as the species quickly depletes available resources, leading to competition among individuals. Additionally, environmental factors or the eventual introduction of predators or diseases can further limit growth, resulting in a population crash as the ecosystem reaches a new equilibrium.
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 the population of a species begins declining rapidly, it often signals underlying issues such as habitat loss, overexploitation, disease, or environmental changes. This decline can lead to reduced genetic diversity, making the species more vulnerable to extinction. Conservation efforts may be necessary to address the threats and help stabilize or restore the population. Prompt action can be crucial in preventing irreversible loss and maintaining ecosystem balance.
