Correct answer: C. 1%
- A. 5%
- B. 3.50%
- C. 1%
- D. 0.20%
Explanation
Only about 1% of the solar energy reaching an ocean is generally converted into primary production because light penetration, nutrients and photosynthetic conditions limit phytoplankton production. Thus 1% is the standard approximate value.
