Marine plants (seaweeds) and many lower organisms have no mechanism to control osmosis, which makes them very sensitive to the salinity of the water in which they live. The main nutrients for plant growth are nitrogen (N as in nitrate NO3 , nitrite NO2 , ammonia NH4 + ), phosporus (P as phosphate PO4 3 ) and potassium (K) followed by Sulfur (S), Magnesium (Mg) and Calcium (Ca).
