What is the term used to describe the process by which pollutants are transported through water?
-
Water pollution
-
Water contamination
-
Water degradation
-

What is the process by which organisms break down dead plants and animals into simpler substances?
-
Decomposition
-
Respiration
-
Photosynthesis
-
Transpiration
A
Correct answer
Explanation
Decomposition is the process by which decomposers, such as fungi and bacteria, break down organic matter into simpler substances.
What is the term used to describe the process by which organisms release waste products into the environment?
-
Excretion
-
Respiration
-
Photosynthesis
-
Transpiration
A
Correct answer
Explanation
Excretion is the process by which organisms release waste products, such as carbon dioxide and urea, into the environment.
What is the process by which spent nuclear fuel is reprocessed?
-
Pyroprocessing
-
Aqueous reprocessing
-
Electrorefining
-
Vitrification
B
Correct answer
Explanation
The most common process for reprocessing spent nuclear fuel is aqueous reprocessing. Aqueous reprocessing involves dissolving spent nuclear fuel in a chemical solution and then separating the uranium and plutonium from the other waste products. The uranium and plutonium can then be reused as nuclear fuel.
What is the term used to describe the process of removing pollutants from the air?
-
Air pollution control
-
Air quality management
-
Odor control
-
Emission reduction
Correct answer
Explanation
Air pollution control refers to the process of removing pollutants from the air, typically through the use of control technologies such as filters, scrubbers, and catalytic converters.
What is the term used to describe the process of controlling odors from industrial or commercial facilities?
-
Air pollution control
-
Odor control
-
Emission reduction
-
Waste management
Correct answer
Explanation
Odor control refers to the process of controlling odors from industrial or commercial facilities, typically through the use of control technologies such as scrubbers, biofilters, and thermal oxidizers.
What is the process of removing excess nutrients from water bodies to reduce eutrophication called?
-
Nutrient stripping
-
Nutrient removal
-
Nutrient management
-
Nutrient remediation
D
Correct answer
Explanation
Nutrient remediation is the process of removing excess nutrients from water bodies to reduce eutrophication.
What is the term used to describe the process of using plants to remove contaminants from soil and water?
-
Phytoremediation
-
Mycoremediation
-
Bioaugmentation
-
Biostimulation
A
Correct answer
Explanation
Phytoremediation is the process of using plants to remove contaminants from soil and water. Plants can absorb contaminants through their roots and then store them in their tissues.

-
Mycoremediation
-
Bioaugmentation
-
Biostimulation
C
Correct answer
Explanation
Bioaugmentation is the process of using microorganisms to break down and remove contaminants from soil and water.

-
Phytoremediation
-
Mycoremediation
-
Bioaugmentation
-
Biostimulation
D
Correct answer
Explanation
Biostimulation is the process of adding nutrients and oxygen to a contaminated site to stimulate the growth of microorganisms that can break down and remove contaminants.
