They cannot be degraded naturally by the action of microorganisms and they stay in the soil for a long time and continue to pollute the soil it with toxic by-products.

. Since these are unnatural products not found in nature there are no organisms capable of decomposing the material so it will not degrade as does other plant and animal waste. Biodegradable waste is decomposed and degraded by microbes. The plastic bags which are extensively used in India are made from recycled plastic.

Why are bacteria and fungi called decomposers. Plastic bags are drastically dangerous for the environment because they are non-biodegradable and it takes many years to decompose. What are the two main components of our environment.

Biodegradable waste are not accumulated but are used up in a short time.

Plastic bags are often mistaken for food by animals birds and marine life. Plastic bag is not acted upon by decomposers as it cannot be broken down into simple components so it is called non-biodegradable while paper gets decomposed. Distinguish between producers and decomposers.

Non-biodegradable materials are not easily affected by the natural process as they do not react with and dissolve in the soil easily. 9 Biodegradable and compostable carrier bags do not to contributesignificantly to biogas formation in landfillsbiogas is a powerful greenhouse gas if released into the atmosphere. That is why pastic bags are called non-biodegradable while paper is not.

Some of these items that are commonly used in day to day lives are plastic products aluminium cans bottles metal scraps glasses grocery bags and Styrofoam polystyrene. Why are plastic bags considered non-biodegradable. Plastic bags are not considered environmentally friendly because they do not decompose easily as decomposer organisms are not able to decompose plastic and make it into a simpler substance which makes it a non-biodegradable product.

They do not contaminate the natural environment by their presence. The consumed plastic congests the digestive tracts of these animals and can lead to health issues such as infections painful intestinal blockage starvation or death by suffocation. Biodegradable substances are the substances that are broken down by biological processes.

Domestic sewage and wood Non-biodegradable. PET is a polyester. Degradation process in Non-Biodegradable waste is slow.

So these plastics dont decay easily. Classify the following as producers and decomposers. Green plants bacteria fungi blue-green algae.

List any two advantages of decomposers to the environment. In case of degradable plastic bags the chemical additives used during the manufacturing of said plastic bags allow the plastic bag to break down much at a much quicker rate as compared to that of a regular plastic bag. Plastic is made from petroleum a product of oil using heat and a catalyst to change the propylene into polypropylene a substance not found in nature.

Also they do not allow water to seep in as they are waterproof. We often use the word environment. Bacteria fungi and a few more abiotic elements like temperature UV oxygen.
