Question

Plastic is one of the most harmful……….waste
(a) Biodegradable
(b) Non- biodegradable
(c)Biotic
(d)Abiotic

Answer 1

Plastics are the synthetic or semi-synthetic materials, which are used for a growing range of applications. It is used worldwide due to its versatile, highly durable, hygienic, flexible, and lightweight properties.

Complete answer:
Plastic is one of the most harmful non-biodegradable waste. These substances cannot be broken down by natural organisms and act as a source of pollution. They do not get degraded by the microorganisms and remain on Earth for thousands of years. They can cause a threat as they can be more critical. Plastic is commonly used in every field which is a non-biodegradable waste. Improved quality plastics are used for giving a long-lasting effect to the plastics which made them more temperature resistant and can be used further. Other materials such as metals and cans for chemicals are the main causes of air, water, and land or soil pollution which causes diseases like cancer. These substances are needed to be replaced as they are not eco-friendly and scientists have to find alternatives for their development.

Additional information:
Biodegradable: The waste material which can be decomposed by bacteria or other natural organisms is biodegradable waste which does not add any pollution to the environment. These wastes get degraded by natural factors such as bacteria, fungi, and other abiotic elements like temperature and UV oxygen. They consist of organic matters which are broken down into carbon dioxide, methane, and water by microorganisms.
Biotic: These factors are the living components that affect organisms and provide the shape to the ecosystem. It constitutes animals that consume organisms within their ecosystem and the organism which are being consumed.
Abiotic: These factors include all non-living factors that are present in the atmosphere and have a significant impact on the survival and reproduction of certain species in an ecosystem.

So, the correct answer is 'Non - Biodegradable'.

Note: There are around 10 metric tons of plastic fragments that are carried out into the Pacific Ocean in Los Angeles every day. The amount of plastic thrown away each year equals to circle the earth four times. Plastic in the ocean killed around 100000 Marine mammals and seabirds annually.
