Explain how adaptations and instincts together help a species survive in its habitat

Adaptations (physical traits) help organisms survive in their environment (for example, water-storing stems in deserts), while instincts (inborn behaviors) guide actions that increase survival (such as escaping predators). Together they increase an organism’s chances of finding food, avoiding danger, and reproducing
