Detailed explanation-1: -Examples include the long necks of giraffes for feeding in the tops of trees, the streamlined bodies of aquatic fish and mammals, the light bones of flying birds and mammals, and the long daggerlike canine teeth of carnivores. All biologists agree that organismal traits commonly reflect adaptations.
Detailed explanation-2: -An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves. Seasonal migration is an example of a behavioral adaptation.
Detailed explanation-3: -An adaptation is defined as a physical or behavioral feature of an animal that helps them better survive in their environment. In other words, an adaptation is something on their body or something they do with their bodies that help them find food, water, mates, and shelter.
