Answer:

c. remain the same

Step-by-step explanation:

Since DDT is persistent and does not break down when release into the environment, it is expected that its concentration as passes along the food chain will likewise persist.

  1. If a substance is non-biodegradable, when it enters the body system or any living tissue, it passes on as waste.
  2. Such matter is not broken down or transformed into another type.
  3. Over many years, it will remain as it is.
  4. We can picture this problem by using non-biodegradable plastics.
  5. They remains just the same in the environment.
