A
Birds fly south for the winter.
B
Lizards play dead when enemies approach.
C
Giraffes have long necks to reach leaves in tall trees.
D
Squirrels store nuts for the winter.
Explanation: 

Detailed explanation-1: -A famous example of a structural adaptation is a giraffe’s long neck. The giraffe has evolved its impressive neck so it can eat leaves from the tallest trees. This means it doesn’t have to compete for food with other animals, giving it the best chance of survival.

Detailed explanation-2: -The giraffe’s long neck is a perfect adaptation to the animal’s natural habitat. Clearly the giraffe evolved this uncommon and helpful trait in order to reach those nourishing leaves. That’s how natural selection works.

Detailed explanation-3: -The long neck of the giraffe has been held as a classic example of adaptive evolution since Darwin’s time.

Detailed explanation-4: -Feeding. With the aid of its long neck, a giraffe is able to reach leaves, fruit and flowers high up in Vachellia or Senegalia (formerly Acacia) and other sought after tree species. Giraffe are thus equipped to exploit a band of foliage beyond the reach of all other terrestrial browsers, except for elephant.
