Which term describes high nutrients, high productivity, green and turbid water?

Which term describes high nutrients, high productivity, green and turbid water?

• A. Eutrophic
• B. Oligotrophic
• C. Mesotrophic
• D. Hypereutrophic

Answer: (A)

Freshwater trophic states describe how nutrient availability drives plant and algal growth and water clarity. High nutrient levels fuel rapid primary production, leading to dense algal blooms that give the water a green tint and increase turbidity as cells and other particles scatter light. This combination of high nutrients, high productivity, and green, turbid water is characteristic of eutrophic systems. In contrast, waters with low nutrients are oligotrophic and tend to be clear with low productivity, mesotrophic are intermediate, and hypereutrophic describes an extreme level of nutrients and blooms with even more severe turbidity and ecological impacts.
