Question 1:

What is the primary characteristic of biodegradable polymers?

Explanation: The primary characteristic of biodegradable polymers is their ability to break down by natural processes. Biodegradable polymers can be decomposed by microorganisms into simpler compounds, reducing their environmental impact.

Question 2:

Which of the following is an example of a biodegradable polymer?

Explanation: Polylactic acid (PLA) is an example of a biodegradable polymer. PLA is derived from renewable resources such as corn starch or sugarcane and can be broken down by microorganisms in composting facilities.

Question 3:

What is the potential environmental impact of non-biodegradable polymers?

Explanation: The potential environmental impact of non-biodegradable polymers is their contribution to landfill waste. Non-biodegradable polymers take a long time to decompose, leading to the accumulation of plastic waste in landfills and the environment.

Question 4:

What are microplastics?

Explanation: Microplastics are small particles of plastic, typically less than 5 millimeters in size. They can come from the breakdown of larger plastic items or be intentionally manufactured as microbeads for use in personal care products.

Question 5:

Why is the presence of microplastics in the environment a concern?

Explanation: The presence of microplastics in the environment is a concern because they can be ingested by organisms and cause harm. Microplastics can accumulate in the bodies of organisms, potentially disrupting their digestive systems or transferring harmful chemicals into the food chain.
