5. What is an adaptation? List an example of a plant adaptation.
An adaptation is a characteristic or feature that an organism develops over time to help it survive and reproduce in its environment. It is a result of the process of natural selection.
An example of a plant adaptation is the presence of thorns or spines on plants. Thorns and spines help protect plants from being eaten by herbivores, such as animals, by acting as a physical deterrent. They also reduce water loss from the plant's surface by reducing the surface area exposed to the environment, thereby helping the plant conserve water.
