  1. Bioaccumulation

  2. Biomagnification

  3. Biodegradation

  4. Bioremediation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bioremediation refers to the use of microorganisms to break down and remove pollutants from the environment.

Multiple choice

Which of the following is NOT a type of bioremediation?

  1. Phytoremediation

  2. Mycoremediation

  3. Bioaugmentation

  4. Bioaccumulation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bioaccumulation is the process by which organisms accumulate pollutants in their tissues, rather than transforming or removing them from the environment. It is not a form of bioremediation.

Multiple choice
