Organisms adapt to their environments in order to survive and reproduce. Adaptations can be structural, such as frogs adapting to live on land and in water or rose bushes growing thorns to protect themselves from predators. Frogs are cold-blooded and found in a variety of climates while rose bushes grow thorns modified from leaves to deter animals from eating their foliage. Adaptations help organisms find suitable habitats and protect themselves against threats in their environments.
