C Correct answer
Explanation

Visible light is the primary source of energy for photosynthesis in plants, which convert it into chemical energy through the process of photosynthesis.

Multiple choice

What is the term for the process by which marine organisms produce oxygen through photosynthesis?

  1. Primary production

  2. Secondary production

  3. Tertiary production

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

Primary production is the process by which marine organisms produce oxygen through photosynthesis. Photosynthesis is the process by which plants and other organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. Primary production is the foundation of the marine food web.

Multiple choice

What is the term used to describe the process by which plants absorb carbon dioxide from the atmosphere during photosynthesis?

  1. Carbon Sequestration

  2. Carbon Fixation

  3. Carbon Capture and Storage

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

Carbon Fixation is the process by which plants absorb carbon dioxide from the atmosphere during photosynthesis. This process converts carbon dioxide into organic compounds, which are used by plants for growth and energy production.

Multiple choice

Which of the following is NOT a type of microbial photosynthesis?

  1. Oxygenic photosynthesis

  2. Anoxygenic photosynthesis

  3. Cyclic photophosphorylation

  4. Non-cyclic photophosphorylation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cyclic photophosphorylation is not a type of microbial photosynthesis, but rather a process that occurs in plants to generate ATP.
