Husk refers to the outer shell or protective covering of certain fruits, seeds, or grains. It serves as a barrier that protects the inner edible parts from pests, diseases, and environmental factors. Common examples of husks include the outer layers of corn, rice, and sunflower seeds. In agriculture, removing the husk is an important step in processing these crops for consumption. The husk can also be used in various applications, such as animal bedding or as a natural mulch in gardening. Additionally, some cultures utilize husks in traditional crafts or as a material for making biodegradable products.
