The term 'become decayed' can be summarized by the word 'ROT', which is a 3-letter word. ROT is a process of decomposition of organic material caused by bacteria, fungi, or other microorganisms. It is a natural process that breaks down dead plants and animals into simpler forms of matter. Rotting can also refer to the deterioration of materials due to age or exposure to the elements. In either case, the result is a gradual breakdown of the material, leading to its eventual decay.
