Answer:
D) solubility
Explanation:
The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is it's solubility!
The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute.
This is exactly what happens when you put too much sugar on your tea! The sugar precipitates when it reaches the water's solubility point!
Organisms only require small amounts of nutrients in biological treatment, so there normally is an excess available in treated wastewater. In severe cases, excessive nutrients in receiving waters cause algae and other plants to grow quickly depleting oxygen in the water.. Hope this helped
