  1. Bioaccumulation

  2. Biomagnification

  3. Bioconcentration

  4. Biotransformation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biomagnification is the process by which pollutants become more concentrated in organisms at higher trophic levels in the food chain.

Multiple choice

  1. Emission

  2. Discharge

  3. Leakage

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Emission, discharge, and leakage are all terms used to describe the process by which pollutants are released into the environment.

Explanation

Detoxification is the process by which pollutants are transformed into less harmful substances.

Multiple choice

What is the term used to describe the process by which pollutants are transported from one place to another?

  1. Dispersion

  2. Diffusion

  3. Advection

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dispersion, diffusion, and advection are all terms used to describe the process by which pollutants are transported from one place to another.

Multiple choice

What is the term used to describe the process by which pollutants are removed from the environment by natural processes?

  1. Bioremediation

  2. Phytoremediation

  3. Mycoremediation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bioremediation, phytoremediation, and mycoremediation are all terms used to describe the process by which pollutants are removed from the environment by natural processes.

Multiple choice

What is the term used to describe the process of removing contaminants from soil?

  1. Bioremediation

  2. Phytoremediation

  3. Excavation

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

Bioremediation is a process that uses microorganisms to break down and remove contaminants from soil. Phytoremediation is a similar process that uses plants to absorb and remove contaminants from soil. Excavation and landfilling are methods of removing contaminated soil from a site, but they do not involve the removal of contaminants from the soil itself.

Multiple choice

What is the term used to describe the process of breaking down organic matter in soil?

  1. Decomposition

  2. Mineralization

  3. Nitrification

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

Decomposition is the process by which organic matter in soil is broken down by microorganisms into simpler compounds. Mineralization is the process by which organic matter is converted into inorganic compounds, such as nitrates and phosphates. Nitrification is the process by which ammonia is converted into nitrates. Denitrification is the process by which nitrates are converted into nitrogen gas.

Multiple choice

What is the term used to describe the process of converting organic matter into a nutrient-rich soil amendment?

  1. Composting

  2. Manuring

  3. Mulching

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

Composting is the process of converting organic matter, such as food scraps, yard waste, and paper products, into a nutrient-rich soil amendment. Manuring is the process of adding manure to soil to improve soil fertility. Mulching is the process of covering the soil with a layer of organic material to help retain moisture and suppress weeds. Fertilizing is the process of adding nutrients to soil to improve plant growth.

Multiple choice

What is the term used to describe the process of removing contaminants from soil using plants?

  1. Bioremediation

  2. Phytoremediation

  3. Excavation

  4. Landfilling
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Phytoremediation is the process of using plants to remove contaminants from soil. Bioremediation is the process of using microorganisms to remove contaminants from soil. Excavation and landfilling are methods of removing contaminated soil from a site, but they do not involve the removal of contaminants from the soil itself.

Multiple choice

What is the term used to describe the process of breaking down oil spills using microorganisms?

  1. Biodegradation

  2. Photodegradation

  3. Evaporation

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

Biodegradation is the process by which naturally occurring microorganisms, such as bacteria and fungi, break down and utilize oil compounds as a food source, leading to the gradual removal of oil from the environment.

Multiple choice
