Explanation:

DDT is a persistent organic pollutant. It is resistant to degradation by natural processes (such as microbial breakdown) in the environment. In contrast, a peanut - butter and jelly sandwich, a plain paper bag, and a partially eaten apple are organic materials that can be decomposed relatively quickly by biological agents (like bacteria and fungi) in the environment.

DDT and other chemicals like it
