Answer 1

Purple loosestrife is an exotic or non-native species that's become invasive in North American wetlands, negatively affecting native wildlife and plants.

Step-by-step explanation:

Purple loosestrife, a non-native species to North America, has become problematic in many wetlands where it dominates the ecosystem, causing a decrease in populations of native plants and animals such as cattails, canvasback ducks, and bog turtles.

Introduced as an ornamental plant, purple loosestrife is now considered an invasive species because of its ability to outcompete native plants and alter the native plant community structure. The correct answer to the question is A. an exotic species.
