The observation that reeds growing in a freshwater swamp in Louisiana are being replaced by cattail plants best illustrates competition between species. In this scenario, reeds and cattail plants are different species with similar requirements for growth. As they both compete for resources such as space, nutrients, and sunlight in the same habitat, the cattail plants outcompete the reeds and replace them over time. This is a clear example of interspecific competition, where different species compete for the same limited resources within an ecosystem.
