Environmental and Chemical Processes Questions
What is the term for the process of converting organic waste into a valuable resource?
-
Composting
-
Anaerobic digestion
-
Incineration
-
Landfilling
A
Correct answer
Explanation
Composting is the process of converting organic waste into a valuable resource, such as compost, which can be used as a soil amendment.
What is the process of using plants to absorb and remove pollutants from the soil and water called?
-
Bioremediation
-
Phytoremediation
-
Mycoremediation
-
Gene therapy
B
Correct answer
Explanation
Phytoremediation is the process of using plants to absorb and remove pollutants from the soil and water. Plants can absorb pollutants through their roots and leaves, and then break them down and store them in their tissues.
Which biotechnology technique involves the use of enzymes to break down and remove pollutants from the environment?
-
Bioremediation
-
Phytoremediation
-
Mycoremediation
-
Enzyme technology
D
Correct answer
Explanation
Enzyme technology involves the use of enzymes to break down and remove pollutants from the environment. Enzymes are biological catalysts that can speed up chemical reactions, including the breakdown of pollutants.
What is the process of using bacteria to break down and remove pollutants from the environment called?
-
Bioremediation
-
Phytoremediation
-
Mycoremediation
-
Bacterial remediation
D
Correct answer
Explanation
Bacterial remediation is the process of using bacteria to break down and remove pollutants from the environment. Bacteria can secrete enzymes that break down pollutants into harmless substances.
Which biotechnology technique involves the use of fungi to absorb and remove pollutants from the environment?
-
Bioremediation
-
Phytoremediation
-
Mycoremediation
-
Fungal remediation
D
Correct answer
Explanation
Fungal remediation is the process of using fungi to absorb and remove pollutants from the environment. Fungi can absorb pollutants through their cell walls and then break them down and store them in their tissues.

What is the term used to describe the process of removing organic matter from water?
-
Ozonation
-
Filtration
-
Disinfection
-
Activated carbon adsorption
D
Correct answer
Explanation
Activated carbon adsorption is a common method for removing organic matter from water. It involves passing water through activated carbon, which is a highly porous material that adsorbs organic compounds onto its surface.
What is the process of converting organic matter into biogas called?
-
Composting
-
Anaerobic digestion
-
Incineration
-
Pyrolysis
B
Correct answer
Explanation
Anaerobic digestion is the process of converting organic matter into biogas in the absence of oxygen. This process is carried out by microorganisms, such as bacteria and archaea, which break down the organic matter into simpler compounds, including methane and carbon dioxide.
