Question

Bioremediation is a process used to:

• A. Increase crop yield using synthetic fertilizers
• B. Treat environmental pollutants using microorganisms
• C. Control noise pollution in urban areas
• D. Enhance fossil fuel combustion efficiency

Hint:

Bioremediation uses natural processes to break down or neutralize pollutants.
Microorganisms, fungi, and plants are key agents in this process.
It is important to understand that bioremediation is specifically used for treating environmental contaminants like oil, heavy metals, and other pollutants.

Answer 1

The Correct Option is B

To determine the correct answer, let's first understand the concept of bioremediation and then analyze the given options.
Step 1: Understand Bioremediation
Bioremediation is a biological treatment process that uses microorganisms, plants, or enzymes to remove or neutralize pollutants from contaminated environments. It is commonly used to treat soil, water, and air polluted with hazardous substances such as oil, heavy metals, and other organic contaminants.
Step 2: Analyze Option A - Increase crop yield using synthetic fertilizers
This option refers to the use of synthetic fertilizers, which is not related to bioremediation. While fertilizers help increase crop yield, they do not treat pollutants or improve environmental conditions.
Thus, option A is incorrect.
Step 3: Analyze Option B - Treat environmental pollutants using microorganisms
Bioremediation specifically involves the use of microorganisms, fungi, or bacteria to break down and detoxify pollutants in the environment. This process can be applied to treat soil, water, and even air pollution.
Therefore, option B is the correct answer.
Step 4: Analyze Option C - Control noise pollution in urban areas
Noise pollution is a type of environmental pollution, but it is not addressed by bioremediation. Bioremediation focuses on pollutants that can be biologically degraded, not noise.
Thus, option C is incorrect.
Step 5: Analyze Option D - Enhance fossil fuel combustion efficiency
Enhancing fossil fuel combustion efficiency is related to energy production and optimization, but it does not fall under bioremediation. Bioremediation is concerned with the removal or neutralization of pollutants, not improving combustion processes.
Thus, option D is incorrect.
Step 6: Conclusion
Bioremediation specifically involves the use of microorganisms to treat environmental pollutants. Therefore, the correct answer is option B, which accurately describes the process.
