| Brief text description | Freshwater algae preferentially uptake ammonium nitrogen when Ammonium and Nitrate are present. |
| Long text description | For nitrogen, both nitrate and ammonium can be taken up, but freshwater algae preferentially uptake ammonium nitrogen when both are present. Nitrate nitrogen can nonetheless be an important source of nitrogen. |
