What is used in composting?

Answer and explanation

Correct answer: Organic waste

The governing concept is biological decomposition of organic matter. Composting uses biodegradable materials such as food scraps, fruit and vegetable peels, grass, and dry leaves. Bacteria, fungi, and other decomposers break these materials into simpler substances under suitable conditions of moisture, air, and temperature. The resulting compost can improve soil structure and provide organic nutrients. Therefore, option B is correct. Glass pieces, an iron nail, and a plastic bottle are not suitable compost ingredients because they do not decompose like organic matter; they should instead be separated for reuse, recycling, or safe disposal. Composting also reduces the amount of wet waste sent to landfills.
