Multiple choice

What is the term used to describe the process by which organic molecules are formed from inorganic molecules?

  1. Abiogenesis

  2. Biogenesis

  3. Photosynthesis

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

Abiogenesis is the process by which organic molecules are formed from inorganic molecules. It is a complex and poorly understood process, but scientists believe that it may have occurred in hydrothermal vents or other environments on early Earth.

Multiple choice

What is the term used to describe the process by which carbon dioxide dissolves in seawater and forms carbonic acid?

  1. Ocean Acidification

  2. Carbonate Buffering

  3. Ocean Alkalinity

  4. Ocean Carbon Cycle
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ocean Acidification refers to the ongoing decrease in the pH of seawater due to the absorption of atmospheric carbon dioxide.

Multiple choice

What is the term used to describe the process by which marine organisms remove carbon dioxide from the atmosphere and convert it into organic matter?

  1. Ocean Acidification

  2. Carbon Sequestration

  3. Ocean Alkalinity

  4. Ocean Carbon Cycle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbon Sequestration refers to the process by which marine organisms, particularly phytoplankton, absorb carbon dioxide from the atmosphere and convert it into organic matter through photosynthesis.

Multiple choice

What is the term used to describe the process by which marine organisms release carbon dioxide back into the atmosphere?

  1. Ocean Acidification

  2. Carbon Sequestration

  3. Ocean Alkalinity

  4. Ocean Carbon Cycle
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Ocean Carbon Cycle refers to the continuous exchange of carbon between the ocean and the atmosphere, including processes such as carbon sequestration and the release of carbon dioxide through respiration and decomposition.

Multiple choice

What is the term used to describe the process by which marine organisms convert organic matter into inorganic nutrients?

  1. Ocean Acidification

  2. Carbon Sequestration

  3. Ocean Alkalinity

  4. Ocean Carbon Cycle
Reveal answer Fill a bubble to check yourself
D Correct answer
