Verified step by step guidance

Step 1: Understand the concept of invasive species. An invasive species is a non-native organism introduced to an ecosystem where it causes harm to the environment, economy, or human health. Native species, on the other hand, are naturally found in a specific region and are part of the ecosystem's balance.
Step 2: Analyze the options provided. Determine which species are native to the region mentioned and which are non-native and causing harm. For example, the bald eagle (Haliaeetus leucocephalus) is native to North America, while the European starling (Sturnus vulgaris), kudzu vine (Pueraria montana), and zebra mussel (Dreissena polymorpha) are non-native and have been introduced to their respective regions.
Step 3: Evaluate the ecological impact of each species. Invasive species like the European starling, kudzu vine, and zebra mussel disrupt ecosystems by outcompeting native species, altering habitats, or causing economic damage. Native species like the bald eagle do not fit this definition.
Step 4: Identify the species that is NOT considered invasive. Since the bald eagle is native to North America and does not cause harm as an introduced species, it is the correct answer to the question.
Step 5: Conclude that understanding the distinction between native and invasive species is crucial for ecological studies and conservation efforts. This knowledge helps in identifying and managing species that threaten biodiversity and ecosystem health.
