Detailed explanation-1: -Bacteria and certain fungi use the decaying remains of plants and animals as their food. In the process of digesting it, complex organic molecules are broken down to simple organic and inorganic molecules. This breakdown by biological process is known as biodegradation.
Detailed explanation-2: -The substances such as plastics and metals which cannot be broken down by the biological process are called non-biodegradable substances.
Detailed explanation-3: -Biological recycling, or biorecycling, is an emerging technology that uses microbes, such as bacteria or fungi, to break down plastic into its basic components for reuse.
Detailed explanation-4: -Biodegradable wastes are such waste materials which are and can be degraded by natural factors like microbes (e.g. bacteria, fungi and a few more), and abiotic elements like temperature, UV, oxygen, etc. Some examples of such wastes are food materials, kitchen wastes, and other natural wastes.
Detailed explanation-5: -Biodegradable materials are substances that can be decomposed or broken down by microorganisms and other living organisms.
