coral reffes are better
Living coral must remain relatively close to the surface of the water so that the symbiotic algae can have access to sunshine. The algae requires sunshine in order to complete photosynthesis which provides oxygen to the coral.
Coral and algae (specifically the algae called zooxanthellae) have an intimate symbiotic relationship. The algae live inside the coral, and provide it with sugars and other photosynthesis byproducts. The coral provides the algae with nutrients for photosynthesis and a safe place to live and reproduce.
Commensalism
there is no animal can survive
Coral polyps and Zooxanthellae. They have a symbiotic relationship with each other. The coral polyps provide a home for the Zooxanthellae (a type of algae) and the Zooxanthellae provide the polyp with food and gives the coral its recognizable color. Without the Zooxanthellae, coral bleeching occurs.
Algae are in a symbiotic relationship with coral.Parrotfish, butterfly fish, angelfish, sea slugs, snails, worms and the crown-of-thorns starfish all eat coral.
only man
The eel hides in the coral. The eel eats the animals trying to eat the coral, and gets food and protection from predators. This is called a mutual relationship.
I am kinda positive that algae is a symbiotic factor.
symbiotic algae
nothing...LOL
