it is limited
Phosphorus is the main limiting nutrient in freshwater environments, whereas nitrogen is the main limiting nutrient in saltwater environments.
In saltwater environments, nitrogen is typically the limiting nutrient due to its scarcity in seawater, while in freshwater environments, phosphorus is commonly the limiting nutrient because it is less abundant and can restrict primary productivity. Both nutrients are essential for plant growth and are closely monitored in ecosystem management.
Approximately 97% of the Earth's water is saltwater found in oceans, with only about 3% being freshwater. Out of this 3% freshwater, the majority is locked in glaciers and ice caps, leaving a lesser amount available in lakes, rivers, and underground sources for human use.
The boiling point of saltwater is higher than that of freshwater. This is because adding salt increases the boiling point of water. The exact boiling point increase depends on the concentration of salt in the water.
Freshwater typically has lower levels of dissolved solids compared to saltwater. Saltwater contains higher concentrations of salt (sodium chloride) and other dissolved minerals, making it more saline. This difference in dissolved solids affects the density and freezing point of the water.

Yes and no. More or less freshwater than where?? You can't compare unless you have something to compare against. Is your question whether or not there is more freshwater underground or above ground?
Displaying the nutrient content in this way makes it easier to compare different foods or products.
Estuaries are highly productive ecosystems due to the mixing of freshwater and saltwater, providing habitats for diverse plant and animal species. Their high productivity supports rich biodiversity and contributes significantly to global carbon cycling. Compared to other areas, such as open oceans or deep-sea environments, estuaries typically have higher primary productivity and support a greater abundance of marine life.
They compare, because of the audit molecular structure of the raid forest atom, is being molecules in the anus. That is how. My niggard.
Air, moisture and nutrient content are ways to compare compost and soil. Soil can be nutrient- and water-deficient in the case of sand and nutrient- and water-retentive in terms of clay and loam. Dark-colored, fresh-smelling, nutrient-rich compost may be added to correct air, moisture and nutrient deficiencies or excesses through amending, fertilizing or mulching actions.
it depends on the circumstances. boat type, wind..... In a controlled environment where water temp,current, and wind are equal you will be faster in fresh water. this is because fresh water is less dense thus creating less resistance. on the other hand you float higher in saltwater which can also create less drag. However mathematically because of the resistance of saltwater you can calculate that you will be able to go faster in fresh water despite floating higher in saltwater. Its not much faster. I haven't calculated it but if I had to guess maybe 1-2% faster. A more dramatic example would be easier to understand. lets compare freshwater vs mud or somewhat diluted mud 50 50. its a lot easier to figure out which you will go faster in. My boat will practically sit on top of the mud. less drag right? This is what most people think saltwater does for them. How fast are you going to go in mud? Not hard to figure that out. there is too much resistance, you probably wont go anywhere. Apply this same logic to saltwater vs fresh and you can see that the more dense a solution is the more resistance it will have.
