Explanation of correct option: • A substance that can be broken down by bacteria or other natural creatures without contributing to pollution is said to be biodegradable. • Wool grass and paper are examples of biodegradable substances. • They do not contribute to pollution and decompose to improve the fertility of the soil. Explanation of incorrect options: Option B: • Polythene, detergent, and PVC are examples of non-biodegradable substances. • A non-biodegradable material is any form of substance that is a cause of pollution and cannot be degraded by natural organisms. ...
Question 1Which of the following groups contain only biodegradable items?1. Glass, flowers and leather2. Grass, wood and plastic3. Fruit peels, cake and lime juice4. Cake, wood and grass
Options 3 and 4 are correct. An item is biodegradable if it can be degraded by biological processes. Degradation by biological processes involves live organisms such as bacteria or fungi. Thus, biodegradable items mean items which can be degraded by using live organisms. Fruit peels, cake, lime juice, wood, grass, flowers, leather, are all of the biological origins and hence they are biodegradable. Glass is degradable but not by biological processes. Glass usually degrades by mechanical processes. Plastic is a polymer of the substances obtained from petroleum products. It is totally non-biodegradable.

Hint: Biodegradable materials are the ones that, through natural processes, can be degraded into certain usable forms. The microorganisms present in our community, such as bacteria and other decomposer organisms (called saprophytes), are unique in their behavior. Materials or items made of natural materials (such as paper, food) are broken down, but man-made materials such as plastics are not broken down. Complete answer: Biodegradable waste is considered waste that is capable of being quickly broken down or decomposed by the actions of microorganisms. The microbes can quickly disassemble fruit peels, cake, lime juice, wood, and grass. Fruits are organic substances which can be introduced by microorganisms and converted into simple organic substances by the process of decomposition. The fruits are made of cellulose and pectin that can be broken down by the microbial enzyme that is secreted. Examples of biodegradable materials include human and animal excreta, plant products such as rubber, paper, wood, leaves, cotton and wool, living organisms' remains, cooking waste, and agricultural waste. Additional Information: Non-biodegradable waste is one that cannot be decomposed or dissolved by natural agents. They have stayed for thousands of years on earth without any deterioration. Examples of non-biodegradable materials include glass, plastics, electrical devices, computer parts, batteries, medical waste, plastic bags, plastic bottles, tetra-packs, and carbon paper.
