The correct answer is D. Immigration is when animals move into an ecosystem.
Explanation:
Animal migration is the movement of animals from one habitat to another, caused by specific needs for food, hibernation, climatic issues, or even to escape predators. Migration, like the migration of birds, is a directed migration, that is, it aims at a specific end; while dispersion is the more or less random distribution of a group of individuals over the habitat. Thus, within the migratory process of animals, two movements are distinguished: emigration, which is the departure of animals from a place, and immigration, which is the entry or arrival of these to the new habitat.
The factor that will prevent the species from becoming an invasive one is predation.
If the species of fish introduced is an apex predator, there will be no organisms present to keep the population of the fish in check. Moreover, if the introduced species has a selective advantage over those that it shares the same niche with, then it is more likely to oust these species from the food chain by consuming all of their resources.
