Which consequence is associated with coral bleaching?

Coral bleaching occurs when corals, stressed by factors such as rising sea temperatures, pollution, or changes in light, expel the symbiotic algae (zooxanthellae) that live within their tissues. These algae are crucial for coral's health as they provide essential nutrients through photosynthesis and contribute to the coral's vibrant colors. When corals bleach, they lose these algae and, consequently, their primary source of food and color, which significantly hampers their ability to thrive.

As a direct consequence of coral bleaching, decreased biodiversity becomes apparent. Coral reefs are among the most diverse ecosystems on the planet, providing habitat and resources for a multitude of marine species. When coral health deteriorates due to bleaching, the structural complexity of the reef diminishes, which in turn leads to a decline in the variety of organisms that rely on the reef for survival. This loss of biodiversity can lead to imbalances in the ecosystem and affect fish populations, invertebrates, and other marine life that depend on healthy coral reefs.

Consequently, the impact of coral bleaching extends beyond just the coral itself, influencing the entire marine ecosystem and leading to a significant reduction in biodiversity. Such ecological consequences highlight the importance of protecting coral reefs and mitigating the stressors that
