Detailed explanation-1: -Coral bleaching happens when corals lose their vibrant colors and turn white. But there’s a lot more to it than that. Coral are bright and colorful because of microscopic algae called zooxanthellae . The zooxanthellae live within the coral in a mutually beneficial relationship, each helping the other survive.
Detailed explanation-2: -This is called coral bleaching. When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
Detailed explanation-3: -Coral reefs are bright and colorful because of the algae that live in them. When water temperatures rise too high, the algae are forced out of the coral, causing the reefs to lose color and potentially die. Coral reefs are home to a vast array of wildlife and help protect communities against floods and storms.
Detailed explanation-4: -What is Coral Reef Destruction? Coral reef destruction is the degradation (and potential mass death) of the ocean’s corals. It is normally caused by illegal fishing techniques, pollution, careless tourism, other natural phenomena such as earthquakes and hurricanes.
Detailed explanation-5: -Warmer waters can trigger a coral bleaching where the coral turns white as it expels the symbiotic food-producing algae living in its tissues. Prolonged bleaching events often cause corals to die from starvation, but they can recover if they reclaim their food source within a few weeks.
