Can submersed weeds grow densely in clear, clean waters with low nutrient content?

Submersed weeds can indeed grow in clear, clean waters with low nutrient content, making it possible for them to thrive in these conditions. While nutrients such as nitrogen and phosphorus typically promote growth, some species of submersed aquatic plants are adapted to environments with lower nutrient availability. These plants often have efficient nutrient uptake mechanisms and can photosynthesize effectively in clear waters where light penetration is high. Therefore, they can establish populations and grow densely even without an abundance of nutrients.

On the other hand, certain aquatic vegetation types may require higher nutrient levels to thrive and can be limited in less fertile waters. Also, while murky waters can support specific types of plant life, it is not a requirement for all submersed weeds. The relationship between light availability and plant growth is vital, as adequate light facilitates photosynthesis, but it is not the sole determinant for growth in low-nutrient scenarios.
