Question

what does biotic mean?
polymer - based
synthetic

non - living

Explanation:

In the context of biology (a subfield of Natural Science), the term "biotic" refers to living components of an ecosystem. "Polymer - based" and "synthetic" are not related to the meaning of biotic. "Non - living" is the opposite (abiotic). So the correct option is the one with "living".

Answer:

C. living (assuming the options are labeled A. polymer - based, B. synthetic, C. living, D. non - living)
