Bioremediation is a process that utilizes which of the following?

Bioremediation is a process that specifically employs natural bacteria or fungi to break down and remove contaminants from the environment, particularly in soil and water. The technique harnesses living organisms to degrade hazardous substances into less toxic or non-toxic forms, making it an effective method for cleaning up polluted sites.

This process is beneficial because it often has minimal environmental impact, can be cost-effective, and relies on naturally occurring microorganisms, which are adapted to the conditions of the contaminated site. By using these biological agents, bioremediation aims to restore the natural balance of the ecosystem while addressing contamination issues.

In contrast, other options such as using chemicals, mechanical means, or heat treatment do not fall under the definition of bioremediation. While these methods can be effective for waste management and pollution control, they do not utilize biological organisms and are therefore outside the scope of bioremediation practices.
