Quizplus · Accepted Answer

An organism can be classified as an indicator based on its range of tolerance and niche. Range of tolerance refers to the range of environmental conditions within which an organism can survive, while niche refers to the specific role an organism plays within its ecosystem. Indicators are organisms that are sensitive to environmental changes and can provide insight into the overall health of an ecosystem. By understanding an indicator species' range of tolerance and niche, scientists can identify potentially harmful changes in the environment. Size and niche do not directly relate to an organism's indicator status.
