Following three months, the urchins and algae were combined together to find out how the lethality of the sea urchin grazing events altered as a function of the acidity and temperature of seawater. The algae also give a coral its color; coral polyps are actually transparent, so the color of the algae inside the polyps show through. Sciences, Culinary Arts and Personal Herbivorous fish and urchins graze reefs to prevent them from becoming overgrown with algae. What is this place, and how does it survive? The Coral Polyps are eaten by a tertiary consumer, the Sea Slug. Coral Reefs are some of the most diverse ecosystems on Earth. Some species of algae occur naturally, interspersed throughout the colorful coral colonies of the reef. NOAA and the State of Hawaii pioneered a method to use native sea urchins and a form of sea-vacuuming to free an urban reef from algal overgrowth. Include corals, urchins, and algae in your food web.
