Which term refers to the role or position of an organism within its environment, including how it obtains resources?

• A. Niche
• B. Habitat
• C. Biotic Factors
• D. Abiotic Factors

Answer: (A)

The main idea being tested is how an organism fits into its environment—the role it plays and how it uses resources. The term that captures this is niche: it describes the organism’s job within the ecosystem, including what resources it uses, how it obtains them, and how it interacts with other living things. A niche encompasses diet, behavior, timing of activities, and its place in the food web, as well as the conditions it tolerates. Habitat, by contrast, is the physical place where the organism lives. Biotic factors are the living components that affect it, like predators or competitors, and abiotic factors are nonliving aspects such as temperature and moisture. Since the question asks for the term that includes how the organism obtains resources and its role in the ecosystem, niche is the best choice.
