Which of the following describes an endangered species?

The correct answer identifies an endangered species as a plant or animal that is in danger of extinction. This definition highlights the critical status of these species, indicating that their population has declined to a level where they face significant threats from various factors such as habitat loss, pollution, climate change, and overexploitation. Recognizing something as endangered calls for urgent conservation efforts to protect its habitat, promote recovery programs, and minimize threats to ensure its survival.

Other choices describe conditions that do not align with the concept of an endangered species. A growing population suggests that a species is thriving rather than at risk. A species thriving in urban areas indicates adaptability and resilience, which is contrary to being endangered. Lastly, a species that is commonly used in agriculture typically benefits from human cultivation and management, rather than facing the threats typical for endangered species. Therefore, defining an endangered species as one in danger of extinction is essential for understanding and implementing conservation strategies.
