Why do synthetic polymers decay slower than biopolymers?
They are weak and unstable.
They are made of natural components.
Decomposers lack enzymes to break them down.
They dissolve quickly in water.

DNA
Protein
Nylon
Starch
Which characteristic best separates biopolymers from synthetic polymers?
Biopolymers are man-made and durable.
Biopolymers are resistant to enzymes.
Biopolymers are natural and biodegradable.
Biopolymers are not found in living things.
