Significance of water -
The productivity and distribution of plants is also heavily dependent on water.
- wherein
For aquatic organisms the quality (chemical composition, pH) of water becomes important. The salt concentration (measured as salinity in parts per thousand), is less than 5 in inland waters, 30-35 in the sea and > 100 in some hypersaline lagoons.
Correct option is 3
