Adaptation is when a plant or animal make modifications to their body to survive in an altered environment. For example, the snow foxes' fur changes depending on the seasons. Another example would be blueberries. They develop thorns in order to protect the berries the plant grows.
Pretty much all plants adapt. If you pay attention, when you put a plant next to the window, and when there's no sunlight shining on it, you should notice that it will start to lean toward the sun.
Hope I helped!
