Final answer:
Three examples of invasive species are the purple loosestrife, the zebra mussel, and the emerald ash borer. These species have had significant impacts on the ecosystems they invade.
Step-by-step explanation:
Three examples of invasive species are the purple loosestrife (Lythrum salicaria), the zebra mussel (Dreissena polymorpha), and the emerald ash borer (Agrilus planipennis). These species have had significant impacts on the ecosystems they invade.
The purple loosestrife is a plant that has invaded wetland areas in North America, outcompeting native plants and reducing habitat for other species. The zebra mussel, originally from Europe, has spread throughout North America's waterways, causing damage to infrastructure, outcompeting native mussels, and altering freshwater ecosystems.
The emerald ash borer, a beetle native to Asia, has decimated ash tree populations in North America, affecting forests and urban green spaces.
