Structural Adaptation
Imagine trying to find the right outfit that keeps you comfortable and dry on a rainy day. Just like how people choose raincoats and umbrellas to protect themselves from getting wet, organisms have physical features that help them survive in their environments. In this analogy, the raincoat acts like the fur of a polar bear that insulates it against the cold, or the waxy leaves of a desert plant that reduce water loss, both of which are structural adaptations that ensure survival in their specific conditions.
