Answer 1

Answer:

The correct answer is "because it came from something living".

Explanation:

Shells are not in fact alive as they are made of calcium carbonate and in some cases α-chitin, two non living materials. However, since mollusks and crustaceans are living beings, shells are considered biotic.
