Which ecosystem is invasive species inhow did it get there?

Invasive species can be found in various ecosystems, including wetlands, forests, and marine environments. They often arrive through human activities, such as global trade, travel, and the release of pets into the wild. For example, the zebra mussel invaded North American waterways, likely introduced via ballast water from ships. These species can disrupt local ecosystems by outcompeting native species for resources and altering habitats.
