Question

Which is the correct sequence in context with the least bio degradable to most biodegradable material?

• A. Bones, Plastic, Paper, Metal Can
• B. Paper, Metal Can, Bones, Paper
• C. Plastic, Metal Can, Bones, Paper
• D. Plastic, Bones, Paper, Metal Can

Answer 1

Answer: (C)

Plastic, Metal Can, Bones, Paper

Plastics and metal cans do not get decomposed by microbial activity, making them the least biodegradable. The proteinaceous part of the bone is biodegradable, whereas the mineral-based part is non-biodegradable. The main components of paper are plant material cellulose, and most plant materials are biodegradable.

Thus, the correct answer is option C.
