Invasive species can make a natural habitat unsuitable for native species by changing its structure or composition. This may mean changed light levels, altered soil chemistry, or increased soil erosion. They can also upset the balance of nutrient cycling, pollination, and energy flow.
Why are invasive species a problem for ecosystems?
Invasive species are harmful to our natural resources (fish, wildlife, plants and overall ecosystem health) because they disrupt natural communities and ecological processes. … The invasive species can outcompete the native species for food and habitats and sometimes even cause their extinction.
