I disagree with the statement that one invasive species cannot significantly change an ecosystem because ecosystems are very large. One invasive species absolutely can significantly alter an ecosystem, regardless of its size, by outcompeting native species for resources, altering habitats, and disrupting food webs. For example, the introduction of the zebra mussel (an invasive species) into the Great Lakes has drastically changed the ecosystem. These mussels filter vast amounts of water, increasing water clarity but removing phytoplankton that form the base of the food web, leading to declines in native fish populations and altering nutrient cycles.
