Explanation;

-Waxes are nonpolar lipids that form protective layers on plants and animals. For example, waxes cover the feathers of some aquatic birds to keep the feathers dry. On the other hand, plants often have leaves coated with waxes to prevent water from evaporating off the plant surface.

-Because of their hydrophobic nature, waxes prevent water from sticking on the surface of these structures.

The water repellant properties of waxes is very useful in the leaves of some plants, in the feathers of birds and also in cuticle of insects. Waxes in plant leaves reduce the amount of water that is lost by the leaves. The wax that is present in the birds' feather prevent them from getting wet with water.
