Explanation:

Nutria are rodents that are originally endemic to South America. During the late 1800s, nutria were introduced intentionally to different bodies of water, such as rivers and streams, in the United States. This caused a significant alteration to the ecosystem as they started to consume the wetland grasses that served as a shelter and food source for numerous native organisms.

Therefore, nutria were introduced intentionally to the new enviroment. Later, the species affected the environmental conditions of that region.
