What term describes using living organisms to remove toxic chemicals from a contaminated site?

• A. Bioremediation
• B. Biotic
• C. Birth rate
• D. Boiler

Answer: (A)

Bioremediation is the process of using living organisms to remove or neutralize toxic chemicals at a polluted site. Microorganisms like bacteria can break down hydrocarbons and other pollutants, turning harmful compounds into less toxic or harmless forms. Plants can also help by absorbing, accumulating, or transforming contaminants in a method known as phytoremediation. This approach can be done in place or by treating material elsewhere, and it’s valued for being relatively environmentally friendly, often cheaper, and less disruptive than physical or chemical cleanup methods. The other options don’t fit: a broad term for living components in ecosystems, birth rate (a demographic concept), or boiler (a heating device) aren’t about cleaning up contaminants using living organisms.
