11 multiple choice 1 point
bioremediation involves:
the use of microorganisms
silt fences
single use plastics
altering the ph of the water

Explanation:

Define bioremediation

Bioremediation is a waste management technique that uses living organisms to neutralize or remove pollutants from a contaminated site. The prefix "bio-" refers to living organisms, and "remediation" means solving a problem or restoring something to its original state.

Identify the active agents

In environmental science and Pollution Management, the primary organisms used for bioremediation are microorganisms, such as bacteria, fungi, or yeast. These microbes break down, degrade, or absorb hazardous substances into less toxic or non-toxic substances.

Evaluate the given options

• the use of microorganisms: This directly aligns with the definition of bioremediation, as microbes are the biological agents used to clean up pollutants.
• silt fences: This is a physical barrier used in construction to control sediment runoff, not a biological treatment.
• single use plastics: These are major contributors to Water Pollution and environmental degradation, rather than a method of cleanup.
• altering the pH of the water: This is a chemical treatment method, not a biological process.

Select the correct option

Based on the analysis, bioremediation specifically involves the use of microorganisms to clean up contaminated environments.

Answer:

• the use of microorganisms (Correct answer)
• silt fences
• single use plastics
• altering the pH of the water
