What is the term for the process by which nutrients are recycled in an ecosystem?
-
Nutrient cycling
-
Decomposition
-
Photosynthesis
-
Respiration
A
Correct answer
Explanation
Nutrient cycling is the process by which nutrients are recycled in an ecosystem, through the decomposition of organic matter and the release of nutrients back into the environment.
What is the term for the process by which organisms break down organic matter into simpler substances?
-
Photosynthesis
-
Respiration
-
Decomposition
-
Nutrient cycling
C
Correct answer
Explanation
Decomposition is the process by which organisms break down organic matter into simpler substances, such as carbon dioxide, water, and nutrients.
What is the term for the process by which organisms use oxygen to break down food and release energy?
-
Photosynthesis
-
Respiration
-
Decomposition
-
Nutrient cycling
B
Correct answer
Explanation
Respiration is the process by which organisms use oxygen to break down food and release energy, in the form of ATP.
What is the term used to describe the process of removing pollutants from the air?
-
Air pollution control
-
Air quality management
-
Air pollution prevention
-
Air pollution monitoring
A
Correct answer
Explanation
Air pollution control refers to the process of removing pollutants from the air. Air quality management involves developing and implementing strategies to improve air quality. Air pollution prevention involves taking steps to reduce the emission of pollutants into the air. Air pollution monitoring involves measuring and tracking air pollution levels.
What is the term used to describe the process of removing Sulfur Dioxide from flue gases?
-
Desulfurization
-
Deionization
-
Dechlorination
-
Denitrification
A
Correct answer
Explanation
Desulfurization refers to the removal of Sulfur Dioxide from flue gases, typically using technologies like flue gas desulfurization (FGD) systems.
What is the term used to describe the process by which pollutants are removed from the atmosphere?
-
Deposition
-
Dispersion
-
Dilution
-
Advection
A
Correct answer
Explanation
Deposition refers to the process by which pollutants are removed from the atmosphere and deposited onto the Earth's surface through mechanisms such as wet deposition (rain and snow) and dry deposition (settling of particles).
What is the term used to describe the process by which pollutants are transported and mixed in the atmosphere?
-
Deposition
-
Dispersion
-
Dilution
-
Advection
B
Correct answer
Explanation
Dispersion refers to the process by which pollutants are spread out and mixed in the atmosphere due to factors such as wind and turbulence.
