The health of aquatic plants is heavily influenced by water quality and the availability of nutrients. Aquatic plants require clean, well-oxygenated water to thrive, as this quality directly affects their growth and ability to perform photosynthesis. Proper nutrient levels, including essential minerals like nitrogen, phosphorus, and potassium, are critical for their development. A deficiency or excess of these nutrients can lead to poor plant health and may cause detrimental conditions like algal blooms or eutrophication, which further impacts the aquatic ecosystem.

While other factors, such as light and temperature, are important for plant health, they cannot compensate for inadequate water quality or nutrient availability. For instance, aquatic plants need access to sufficient light for photosynthesis, but without appropriate nutrient levels in a healthy water environment, their growth will remain stunted regardless of light availability. Therefore, maintaining optimal water quality and nutrient conditions is fundamental for the thriving ecosystem of aquatic plants.
