Which term describes the unique adaptations and behaviors that enable an organism to live in its environment?

• A. Organism
• B. Niche
• C. Habitat
• D. Community

Answer: (B)

Focus on how an organism fits into its environment. The term describes the unique adaptations and behaviors that allow it to live there—the role it plays, how it obtains food, avoids threats, reproduces, and interacts with other species. This combination of traits and actions is what makes a species well-suited to a particular set of conditions in its habitat. For example, a cactus has adaptations like water-storing stems and spines, plus behaviors such as blooming after rains, that together define its niche in a desert ecosystem. The habitat is simply where it lives, the community is all the species in that place, and an organism is the individual itself.
