Aluminium----..

That can be TAKEN back into the earth NATURALLY and so not harm the ENVIRONMENT.....is Called biodegradable .
But it is not possible of Aluminium foil......So 'D' is answer...

Not Biodegradable: Aluminium Foil

Explanation:

Biodegradable substances are those that can be broken down by natural processes and decomposed by microorganisms. These substances are usually organic in nature and include materials such as food waste, paper, and wood. However, there are also substances that are not biodegradable, meaning that they cannot be broken down by natural processes and remain in the environment for a long time. One such substance is aluminium foil.

Why is Aluminium Foil not Biodegradable?

1. Composition: Aluminium foil is made up of metal, which is not organic in nature and cannot be broken down by microorganisms.

2. Resistance to natural processes: Aluminium foil is resistant to natural processes such as sunlight, water, and air, which are necessary for the breakdown of organic materials.

3. Landfill waste: Aluminium foil does not break down in landfills and can remain there for hundreds of years, contributing to the problem of waste accumulation.

4. Environmental impact: The production of aluminium foil requires large amounts of energy and resources, and the disposal of used foil can have a negative impact on the environment.

Conclusion:

In conclusion, while many everyday items such as vegetables and fruits are biodegradable, aluminium foil is not. It is important to be aware of the environmental impact of the products we use and to make choices that are more sustainable and eco-friendly.
