What adaptation do some plants like the pineapple or the kiwi have to
protect themselves?

Answer

Structural adaptations that kiwi and pineapple have include whiskers at the base of their beak to aid in nocturnal navigation. Nostrils at the end of their beak assist them in finding food. The plumage of a kiwi enables them to blend with the undergrowth in the forest, preventing predators from detecting them by sight.
