Final answer:
Invasive species impact ecosystems by outcompeting other organisms, occupying niches, and adapting to changing climates.
Step-by-step explanation:
Invasive species impact ecosystems by outcompeting other organisms for limited resources, occupying niches that other organisms traditionally occupy, and being more capable of adapting to rapidly changing climates. When invasive species enter an ecosystem, they often have no natural predators or competitors, allowing them to reproduce rapidly and dominate available resources. This can lead to a decline in native species populations and a loss of biodiversity. Additionally, invasive species can disrupt ecosystem processes and alter habitats, affecting the overall functioning of the ecosystem. For example, the introduction of the zebra mussel to the Great Lakes has led to significant impacts on native species and the ecosystem as a whole.
