The use of prokaryotes and other organisms to clean up pollutants from soil, air, or water is called ________.

C)bioremediation
D)biocomposting

Question

Quizplus · Accepted Answer

Bioremediation is the use of living organisms to remove or neutralize pollutants from a contaminated site. Prokaryotes, such as bacteria, are often used in bioremediation because they can break down pollutants such as oil, pesticides, or heavy metals into less harmful substances. Choices A and D are not correct because decomposition refers to the natural breakdown of organic materials by microorganisms, and biocomposting refers to the controlled decomposition of organic waste into compost. Choice B, nitrogen fixation, refers to the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use to grow. While this process is important for plant growth, it is not directly related to the removal of pollutants from a contaminated environment.
