01 Why is composting useful for a school?
Answer and explanation
Correct answer: A. Organic waste can be converted into useful compost
Explanation: Composting uses microorganisms to decompose suitable organic materials such as food scraps, leaves, and garden waste into a useful soil amendment. A school can use the finished compost in its garden and reduce the organic waste sent for disposal. Proper composting needs suitable materials, air, moisture, and management; it does not require burning waste. Option A is correct.
