What is the primary consequence of introducing a non-native species to a new habitat?

Introducing a non-native species to a new habitat primarily leads to competition with native species. This introduction disrupts the existing ecological balance, as the non-native species can outcompete native organisms for resources such as food, space, and other essential needs.

The non-native species may bring different advantages, such as faster growth rates, higher reproductive rates, or the ability to exploit resources that the native species cannot, which can lead to a decline in native populations. Over time, this competition can diminish the populations of native species, disrupt local ecosystems, and alter habitat structures.

The idea that local species would become extinct immediately is misleading, as such processes usually occur over a longer time frame and involve various ecological dynamics. Additionally, while a new species may sometimes thrive in its new environment, it is not guaranteed, and the assertion that there will be no impact on local species does not align with ecological principles, as most introductions do result in some level of competition or ecological interaction.
