Final answer:
Bluebonnet is likely not an invasive species, whereas dallisgrass, giant salvinia, and kudzu are examples of invasive species that can have detrimental effects on native ecosystems. (option d is the correct answer).
Step-by-step explanation:
Bluebonnet, as traditionally understood, does not appear to be a typical example of an invasive species. Invasive species are non-native organisms that, when introduced to a new ecosystem, can outcompete native species and disrupt the balance of the ecosystem. Dallisgrass, giant salvinia, and kudzu, on the other hand, are recognized as invasive species.
Dallisgrass (a) is a non-native grass that can dominate pastures and lawns, displacing native vegetation. Giant Salvinia (b) is an aquatic fern that can rapidly cover water surfaces, hindering sunlight penetration and depleting oxygen levels. Kudzu (c), known as "the vine that ate the South," is a fast-growing plant that can overtake and smother native vegetation.
Bluebonnet, representing the native wildflowers in Texas, is not likely an invasive species, while dallisgrass, giant salvinia, and kudzu exemplify the challenges posed by invasive species and the importance of monitoring and managing their impact on local ecosystems.
