Question

The method of filtering air and water using microscopic organisms to remove contaminants is called ______?

1) Filtration
2) Distillation
3) Reverse osmosis
4) Bioremediation

Answer 1

The process of using microscopic organisms to remove contaminants from air and water is called bioremediation, which is distinct from mere filtration that involves physical barriers such as sand and charcoal.

Step-by-step explanation:

The method of filtering air and water using microscopic organisms to remove contaminants is called bioremediation. Filtration, while it does remove small particles from water by passing it through layers of sand, gravel, and charcoal, does not typically employ microscopic organisms for the process. Filtration can be used to reduce organic matter, remove most bacteria, reduce turbidity and color, and remove odors, iron content, and any remaining solids. Conversely, bioremediation actively utilizes microbes to clean up contaminants, therefore making it distinct from other physical or chemical methods like simply filtration, distillation, or reverse osmosis.
