Here's a breakdown:
* Native species: Species that naturally occur in an ecosystem and have evolved alongside other species within that environment.
* Invasive species: Species that are introduced to an ecosystem where they do not naturally occur. They can often outcompete native species for resources, disrupting the balance of the ecosystem.
Here are some examples of invasive species:
* Zebra mussels: Introduced to the Great Lakes of North America, they have caused significant ecological and economic damage.
* Kudzu: A vine introduced to the southeastern United States, it grows aggressively and can smother native plants.
* Burmese pythons: Introduced to the Florida Everglades, they have decimated native populations of small animals.
Invasive species can have a wide range of negative impacts on ecosystems, including:
* Loss of biodiversity: Invasive species can outcompete native species, leading to their decline and even extinction.
* Damage to habitats: Invasive species can alter habitats by changing the structure of vegetation, soil conditions, and water quality.
* Economic losses: Invasive species can damage crops, livestock, and infrastructure, costing billions of dollars annually.
It's important to be aware of the risks of invasive species and take steps to prevent their introduction and spread.
