Question

5. Plastic that is used for making numerous car parts
6. Substances that cannot be decomposed or degraded by decomposers​

Answer 1

Answer:

1. PVC

2. Non Bio-Degradable

Explanation:

1. While the typical car includes many different kinds of plastics, three types of plastic – polypropylene, polyurethan, and PVC – are the most common.

2. Non-biodegradable substances are those chemical substances which are not broken down by the biological means (decomposers). They persist in the environment for a long time, as they are not degraded by the decomposers and cause harm to the members of the ecosystem by causing biological magnification. Non-biodegradable chemicals like fertilizers, pesticides affect the fertility of soil which reduces the crop yield. Whereas, biodegradable substances are broken down by the decomposers because they possess the specific enzymes for their degradation.
