A nutrient is considered limiting when it is in low enough  quantities to prevent organisms from surviving. Organisms need  several different types of nutrients to survive â¦ , but to illustrate  the point, I will simplify it to three basic elements, carbon,  nitrogen, and phosphorus.
A limiting nutrient is a nutrient necessary for plant growth, but available in a concentration insufficient to support continued growth. Once supply of this nutrient is exhausted, plant growth ceases regardless of other remaining nutrient quantities. Any nutrient can become a limiting nutrient in an ecosystem. For algae, the most obvious limiting nutrients are nitrogen, certain metals and phosphorus. Nitrogen removal is an expensive process, involving high energy and chemical costs and specialised equipment.
