What is a potential benefit of improving water quality for coral reefs?

Improving water quality for coral reefs has a significant benefit in the reduction of algae blooms. When water quality is enhanced, particularly through reduced pollution and nutrient loads, it directly impacts the balance of the marine ecosystem. High levels of nutrients, particularly nitrogen and phosphorus, often lead to excessive growth of algae, which can smother corals and outcompete them for light and space.

By improving water quality, the nutrient levels in the water can be stabilized, which helps to control algae populations. This creates a healthier environment where corals can thrive. Corals rely on a symbiotic relationship with zooxanthellae, the microorganisms that live within their tissues and provide them with essential nutrients through photosynthesis. When algae blooms proliferate, they can block sunlight and release toxins that harm corals, leading to decreased health and growth rates.

Thus, reducing algae blooms through better water quality is crucial for the overall health of coral reefs, allowing for increased biodiversity and resilience of the coral ecosystem.
