A group of individuals of the same species living in a given area?

• A. Intertidal Zone
• B. Population
• C. Habitat
• D. Niche

Answer: (B)

The main idea is a population: a population is a group of individuals of the same species living in a defined area at the same time. This helps distinguish it from other ecological concepts. A habitat is the physical place where organisms live and can contain many species, while a niche describes the role and adaptations of a species within that environment. For example, the intertidal zone is a coastal habitat that can host multiple populations, but it isn’t itself a population. All the mussels of one species living on that rocky shore constitute a population.
