The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that wastes such as plastics, paper, and vegetable or fruit peels generated in our homes daily are biodegradable. - To evaluate this, we need to identify which of these materials are biodegradable. 2. **Evaluating the Materials**: - **Plastics**: Plastics are synthetic materials that do not decompose naturally and are considered non-biodegradable. - **Paper**: Paper is made from wood pulp and can decompose naturally, making it biodegradable. - **Vegetable or Fruit Peels**: These are organic materials that can also decompose naturally, thus they are biodegradable. 3. **Conclusion on Assertion (A)**: - Since plastics are non-biodegradable, the assertion that all the mentioned wastes are biodegradable is **false**. 4. **Understanding the Reason (R)**: - The reason states that biodegradable wastes can be broken down into simpler, harmless substances in nature over time by biological processes, such as the action of microorganisms. - This statement is accurate because microorganisms, through their enzymatic activity, can decompose biodegradable materials into harmless substances. 5. **Conclusion on Reason (R)**: - The reason provided is **true** as it correctly describes the process of biodegradation. 6. **Final Evaluation**: - Since the assertion (A) is false and the reason (R) is true, the correct answer is that the assertion is incorrect while the reason is correct. ### Final Answer: - Assertion (A) is false, and Reason (R) is true.
### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that wastes such as plastics, paper, and vegetable or fruit peels generated in our homes daily are biodegradable. - To evaluate this, we need to identify which of these materials are biodegradable. 2. **Evaluating the Materials**: - **Plastics**: Plastics are synthetic materials that do not decompose naturally and are considered non-biodegradable. ...

Assertion (A): Polythene bags and plastic containers are non-biodegradable substances. Reason (R): They can be broken down by micro organisms in natural simple harmless substances.

Unlimited exploitation of nature by man disturbed the delicate ecological balance between the living and non-living components of the biosphere. The unfavourable conditions created by man himself threatened the survival not only of him but also of the entire living organisms on the mother earth. Rehan is an active member of 'Eco club' of his school which is creating environmental awareness amongst the school students, spreading the same in the society and also working hard for preventing environmental degradation of the surroundings. As part of this awareness programme, they are explaining the importance of using different dustbing for biodegradable and non-biodegradable wastes. Generally green duslbing are for biodegradable wastes and blue for non-biodegradable wastes. In the following groups of materials, which group(s) contains only non-biodegradable items? (I) Wood, paper, leather (II) Polythene, detergent, PVC (III) Plastic, detergent, grass (IV) Plastic, bakelite, DDT
