Explanation:
Correct Option: A (Biodegradable)
Justification: Animal dung is biodegradable because it is made up of organic matter which can be broken down naturally by microorganisms, such as bacteria and fungi, in the presence of oxygen. These microorganisms feed on the dung and convert it into simpler compounds, such as carbon dioxide and water, through the process of decomposition. As a result, animal dung can be used as a natural fertilizer in agriculture to improve soil quality and support plant growth. Furthermore, it is an important source of renewable energy in some parts of the world, as it can be used as a fuel for cooking and heating. Therefore, option A is the correct option.
Option B, Non-biodegradable, is incorrect because non-biodegradable materials do not break down naturally and can persist in the environment for long periods of time. Animal dung does break down naturally, hence it is not non-biodegradable.
Option C, Hazardous, is also incorrect because animal dung is not generally considered hazardous to human health or the environment. It is a natural byproduct of animals and is not known to contain any harmful chemicals or substances.
Option D, Toxic, is also incorrect because animal dung is not toxic. While it may contain certain pathogens or bacteria that can be harmful to humans, these can be eliminated through proper handling and processing. Overall, animal dung is a valuable resource that can be used in a variety of ways, making option A the correct choice.
