What term describes changes in physical structure or behavior that allow an animal or plant to survive and reproduce in an environment?

Explanation:
Adaptations are the changes in physical structure or behavior that help an animal or plant survive and reproduce in its environment. These changes can be physical traits like a cactus’s water-storing stem or a bird’s beak shaped for its food, and behaviors like migrating to find food or camouflaging to avoid predators. This idea covers both how an organism’s body and its actions fit the environment to boost survival and offspring numbers, making it the best fit for describing how living things adapt to where they live. The other choices describe processes or parts that don’t capture this broader idea of lasting adjustments that aid survival and reproduction.
