Question

which of the following is non-biodegradable?
orange cores
plastic bottle caps
paper caps
moldy cheese

Explanation:

Biodegradable materials can be broken down by natural processes (e.g., by microorganisms). Orange cores (organic waste), paper caps (made from plant - based materials), and moldy cheese (organic matter) are biodegradable. Plastic bottle caps are made of plastic, which is a synthetic polymer that is not easily broken down by natural processes, so it is non - biodegradable.

Answer:

B. Plastic bottle caps
