Phytoplankton can cause the water to turn green in high quantity due to their high concentrations of chloroplasts. Plankton are so important to water quality because they form the base of the food web for most ponds, even in cases where there is feed supplied. Plankton also influences dissolved oxygen, pH, nitrogen, and the prevention of large aquatic plant growth through shading.
