Corals get their food from algae living in their tissues or by capturing and digesting prey Corals get their food from algae living in their tissues or by capturing and digesting prey. M ost reef-building corals have a unique partnership with tiny algae called zooxanthellae. The algae live within the coral polyps, using sunlight to make sugar for energy.This energy is transferred to the polyp, providing much needed nourishment.

How Coral Reefs Grow Different species of coral grow at different rates depending on water temperature, salinity, turbulence, and the availability of food. The massive corals are the slowest growing species, adding between 5 and 25 millimeters (0.2–1 inch) per year to their length.Branching and staghorn corals can grow much faster, adding as much as 20 centimeters (8 inches) to their branches each year. Coral reefs grow best in warm water (70–85° F or 21–29° C).Corals prefer clear and shallow water, where lots of sunlight filters through to their symbiotic algae. It is possible to find corals at depths of up to 300 feet (91 meters), but reef-building corals grow poorly below 60–90 feet (18–27 meters).ifferent species of coral grow at different rates depending on water temperature, salinity, turbulence, and the availability of food.

- Other animals that live on the coral reef include sea urchins, sponges, sea stars, worms, fish, sharks, rays, lobster, shrimp, octopus, snails and many more. Many of these animals work together as a team like the coral polyps and zooxanthellae. This teamwork is called symbiosis.eefs need calcium from the water to grow, which is more often available in shallow warm waters. PLANTS: The sun is the source of energy for the coral reef ecosystem. Plant plankton, called phytoplankton, algae and other plants convert light energy into chemical energy through photosynthesis.

Coral Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral group is a colony of myriad genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in length. A set of tentacles surround a central mo

- The zooxanthellae living in the soft tissue of a coral polyp use sunlight to produce food through photosynthesis and create a byproduct that the coral can use as food. Thus, zooxanthellae provide corals with food; in return, the coral provides the zooxanthellae with shelter and nutrients. Corals also capture food. At night, they stretch out their stinging tentacles and catch the microscopic organisms that float in the water and digest them in their stomachs. So, corals have two ways of getting food—through zooxanthellae and capturing microscopic organisms.

Coral Reefs Through the photosynthesis carried out by their algae, coral serve as a vital input of food into the tropical/sub-tropical marine food-chain, and assist in recycling the nutrients too. The reefs provide home and shelter to over 25% of fish in the ocean and up to two million marine species.

Is Coral a Producer, Consumer or Decomposer? The tertiary consumers eat secondary consumers and can also sometimes eat primary consumers and producers. Within a coral reef ecosystem, the tertiary consumers are seals, barracudas, sea birds, dolphins, moray eels and sharks. Lastly, the decomposers help to break down the waste within the ecosystem. They help to dissolve dead organisms as well.

Sea Stars Sea stars have a peculiar way of eating. They actually digest their prey outside of their bodies by extruding their stomach out through their mouth and enveloping the prey item. When the meal is digested, the stomach is drawn back into the body.hough the sea star’s skin is hard and bumpy, a predator can eat it whole if its mouth is large enough. Predators with smaller mouths can flip the sea star over and eat the softer underside. Back to the Top. 1  Go to Explore Animals.

Coral reef Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps.

How do sea stars eat? How do sea stars eat? November 18, 2008 by Beach Chair Scientist 4 Comments First, sea stars grip their prey (e.g., bivalves, such as clams and oysters) with their suction feet and pry them apart to eat the muscle inside the shells. Then, once the bivalve’s shell is open, the stomach of the sea star emerges from the middle of the underside of its star-shaped body to absorb the delicious entrée inside itself.

What Do Sea Sponges Eat? What Sponges Eat. Most sponges are detritivores -- they eat organic debris particles and microscopic life forms that they filter out of ocean water. They're not picky eaters; whatever the ocean current carries their way is what they feast on. Sponges can digest large particles and tiny organisms for sustenance.

How Coral Reefs Work Coral polyps also use the energy supplied by their symbiotic algae to produce calcium carbonate, or limestone. They secrete the limestone from their base, creating a protective skeleton and a hollow chamber called a cup. The polyps retreat into their cup to hide when predators come looking for them.

Sea Turtles Some species change eating habits as they age. For example, green sea turtles are mainly carnivorous from hatching until juvenile size; they then progressively shift to an herbivorous diet. A hawksbill has a narrow head with jaws meeting at an acute angle, adapted for getting food from crevices in coral reefs. They eat sponges, tunicates, shrimps, and squids. Loggerheads' and ridleys' jaws are adapted for crushing and grinding.

Corals Tiny plant cells called zooxanthellae live within most types of coral polyps. They provide the coral with foods resulting from photosynthesis. Click the image for a larger view of these cells. Most reef-building corals contain photosynthetic algae, called zooxanthellae, that live in their tissues.The corals and algae have a mutualistic relationship.f the polyps go for too long without zooxanthellae, coral bleaching can result in the coral's death. Because of their intimate relationship with zooxanthellae, reef-building corals respond to the environment like plants.
