Question:
Which factor primarily limits primary productivity in marine ecosystems?
Which factor primarily limits primary productivity in marine ecosystems?
Show Hint
In marine ecosystems,
\[
\boxed{
\text{Nitrogen and Phosphorus} \rightarrow \text{Major limiting nutrients}
}
\]
Updated On: Jul 18, 2026
- Light
- Nitrogen and phosphorus availability
- Oxygen
- Temperature
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Primary productivity in marine ecosystems is mainly limited by the availability of essential nutrients, particularly nitrogen and phosphorus.
When these nutrients are scarce, the growth of phytoplankton and other primary producers is reduced.
Hence,
\[
\boxed{\text{Nitrogen and phosphorus availability}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
