Chapter 18 Extended Response Standardized Test Prep Extended Response Base your answers to parts A & B on the information below. Some species are generalized with regard to their niche, and other species are specialized. Part A Compare the niche of a generalist species with one of a specialist species. Part B Predict how two different herbivores can share the same plant resource.

Extended Response, continued Chapter 18 Standardized Test Prep Extended Response, continued Answer: Part A Generalist species have a broad niche, as they can tolerate a wide range of conditions and use a wide variety of resources. Specialist species can only use specific resources and have more narrowly defined niches. Part B Two herbivores might eat different parts of the plant, or might eat the plant at different times of the year.
