Final answer:
When a non-native species is introduced into a stable ecosystem, competition for resources can lead to an unbalanced ecosystem.
Step-by-step explanation:
When a non-native species is introduced into a stable ecosystem, the most likely outcome is that the native species will have to compete for resources with the non-native species, leading to an unbalanced ecosystem. The non-native species may outcompete the native species for food, habitat, and other resources, causing a decline in the population of native species. This can disrupt the food web and alter the dynamics of the ecosystem.
