Correct option is A
The correct answer is (a) Composting
Explanation:
- Composting is the process by which biodegradable waste is broken down by microorganisms such as bacteria and fungi into nutrient-rich organic matter called compost. This process involves aerobic decomposition, where oxygen is required for the breakdown of organic materials such as food scraps, leaves, and other biodegradable waste. The compost can then be used as a natural fertilizer to enrich soil, improving its structure, moisture retention, and nutrient content.
Information Booster:
- Composting helps in reducing the amount of waste sent to landfills and produces valuable soil conditioner.
- The process of composting requires the right balance of carbon (found in materials like leaves and straw) and nitrogen (found in food waste and green plants).
- It is an environmentally friendly way to recycle organic waste, reducing greenhouse gas emissions associated with landfill waste decomposition.
- Composting also helps reduce the use of chemical fertilizers, making it beneficial for both the environment and agriculture.
- The composting process can take weeks to months, depending on the materials and environmental conditions such as temperature and moisture levels.
- There are different methods of composting, including aerobic composting (requiring oxygen) and anaerobic composting (which occurs in the absence of oxygen).
Additional Information:
- Recycling: Recycling refers to the process of converting waste materials into new products, usually materials like paper, plastic, glass, and metals. It does not apply to organic biodegradable waste, which is handled through composting.
- Reusing: Reusing involves finding new uses for old items.
- Wasting: It simply refers to the act of discarding or misusing resources.
