Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Decomposition is the process by which decomposers, such as fungi and bacteria, break down organic matter into simpler substances.

Multiple choice

What is the term used to describe the process by which organisms release waste products into the environment?

  1. Excretion

  2. Respiration

  3. Photosynthesis

  4. Transpiration
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Excretion is the process by which organisms release waste products, such as carbon dioxide and urea, into the environment.

Multiple choice

What is the process by which spent nuclear fuel is reprocessed?

  1. Pyroprocessing

  2. Aqueous reprocessing

  3. Electrorefining

  4. Vitrification
Reveal answer Fill a bubble to check yourself
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.

Multiple choice

What is the term used to describe the process of removing pollutants from the air?

  1. Air pollution control

  2. Air quality management

  3. Odor control

  4. Emission reduction
Reveal answer Fill a bubble to check yourself
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.

Multiple choice

What is the term used to describe the process of controlling odors from industrial or commercial facilities?

  1. Air pollution control

  2. Odor control

  3. Emission reduction

  4. Waste management
Reveal answer Fill a bubble to check yourself
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.

Multiple choice

What is the process of removing excess nutrients from water bodies to reduce eutrophication called?

  1. Nutrient stripping

  2. Nutrient removal

  3. Nutrient management

  4. Nutrient remediation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nutrient remediation is the process of removing excess nutrients from water bodies to reduce eutrophication.

Multiple choice

Which of the following is NOT a potential application of bioremediation?

  1. Cleaning up oil spills

  2. Removing heavy metals from soil

  3. Detoxifying wastewater

  4. Producing biofuels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Producing biofuels is not a potential application of bioremediation because it does not involve the use of microorganisms to break down or remove contaminants.

Multiple choice

What is the term used to describe the process of using plants to remove contaminants from soil and water?

  1. Phytoremediation

  2. Mycoremediation

  3. Bioaugmentation

  4. Biostimulation
Reveal answer Fill a bubble to check yourself
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.

Multiple choice

What is the term used to describe the process of using microorganisms to break down and remove contaminants from soil and water?

  1. Phytoremediation

  2. Mycoremediation

  3. Bioaugmentation

  4. Biostimulation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bioaugmentation is the process of using microorganisms to break down and remove contaminants from soil and water.

Multiple choice

What is the term used to describe the process of adding nutrients and oxygen to a contaminated site to stimulate the growth of microorganisms that can break down and remove contaminants?

  1. Phytoremediation

  2. Mycoremediation

  3. Bioaugmentation

  4. Biostimulation
Reveal answer Fill a bubble to check yourself
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.

Multiple choice
