Structures or features on plants and animals that allow them to survive and reproduce in their environment.

Structures or features on plants and animals that allow them to survive and reproduce in their environment.

• A. Genetic Traits
• B. Adaptive Behavior
• C. Physical Adaptation
• D. Organ Systems

Answer: (C)

The main idea being tested is how physical features on organisms help them survive and reproduce in their environment. Physical adaptation refers to body parts or structures that have evolved to fit a specific environment, giving advantages in survival and reproduction. Think of features like thorns on a plant to deter herbivores, thick fur for insulation in cold climates, or the streamlined shape of a fish for efficient swimming. These structural traits arise through natural selection because they increase an organism’s fitness in its particular setting. Other options point to inherited traits in general, behavior, or body systems, which are not specifically about the structural features that aid survival, so the best fit is physical adaptation.
