Verified step by step guidance1
Step 1: Understand the term 'invasive species' by breaking it down. An invasive species is a non-native organism introduced to a new environment where it spreads rapidly and disrupts the ecosystem, economy, or human health.
Step 2: Compare the options provided in the question. Eliminate choices that do not align with the definition of an invasive species.
Step 3: Option A describes a native organism endangered due to habitat loss. This does not match the definition of an invasive species, as invasive species are non-native.
Step 4: Option B describes a species restricted to a specific geographic area. This is not relevant to the concept of invasive species, which are characterized by their ability to spread rapidly.
Step 5: Option D describes a non-native organism that integrates harmlessly into a new ecosystem. This does not fit the definition of invasive species, as they cause harm. The correct answer is Option C, which matches the definition of an invasive species.
