Why are some substances biodegradable and some non biodegradable?
Substances are biodegradable if they can be broken down by microorganisms, such as bacteria and fungi, into simpler compounds that can be absorbed by the environment. These substances typically contain natural compounds such as carbohydrates, proteins, and lipids that can be easily broken down by microorganisms.
On the other hand, non-biodegradable substances are those that cannot be broken down by microorganisms. These substances typically contain synthetic compounds, such as plastics and certain types of chemicals, that are not easily broken down by microorganisms. These materials can persist in the environment for a long time, potentially causing harm to living organisms and the ecosystem.
Additionally, biodegradable materials are those that are made of natural compounds like cellulose and starch, while non-biodegradable materials are those that are made of synthetic compounds like plastic and rubber.
In summary, biodegradable substances are those that can be broken down by microorganisms, while non-biodegradable substances are those that cannot be broken down by microorganisms. Natural materials are biodegradable and synthetic materials are non-biodegradable.
Examples of biodegradable and non-biodegradable
- Organic matter such as food scraps and yard waste
- Paper products
- Natural fibers such as cotton and wool
- Animal waste
- Plastic bags and packaging
- Glass bottles and jars
- Metals (such as aluminum cans)
- Synthetic fibers such as nylon and polyester
- Chemical pesticides and fertilizers
- Electronic waste (such as smartphones and computers)
