The primary consumers are the coral polyps, some mollusk species, the zooplankton species, the starfish, the crabs, the sea urchins, the green sea turtle and some smaller fish living in the coral reef system. Within a coral reef ecosystem, the tertiary consumers are seals, barracudas, seabirds, dolphins, moray eels and sharks.

Lastly, the decomposers help to break down the waste within the ecosystem. By breaking down the waste, the decomposers are able to generate new energy that helps to sustain the ecosystem.

Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.

Similarly, a single organism can serve more than one role in a food web. Food webs consist of different organism groupings called trophic levels.

Detritivores and decomposers complete the cycling of energy through the food web. These nutrients are used by the producers during photosynthesis to create energy, thus completing the cycle.

Answer The intermediate consumers are the sergeant major, flaming tongue snail, bar jack, grouper, Caribbean lobster, bi color dam selfish, polytheists worm, cushion sea star, and southern stingray. Identify the top predator in the coral reef food web illustration.

Corals are sessile animals that “take root” on the ocean floor. When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white.

Corals are sessile, which means that they permanently attach themselves to the ocean floor, essentially “taking root” like most plants do. Corals actually comprise an ancient and unique partnership, called symbiosis, that benefits both animal and plant life in the ocean.

Corals have tiny, tentacle-like arms that they used to capture their food from the water and sweep into their inscrutable mouths. Because of this cycle of growth, death, and regeneration among individual polyps, many coral colonies can live for a very long time.

More than merely a clever collaboration that has endured between some of the tiniest ocean animals and plants for some 25 million years, this mutual exchange is the reason why coral reefs are the largest structures of biological origin on Earth, and rival old-growth forests in the longevity of their ecological communities. Other animals in this group that you may have seen in rock pools or on the beach include jelly fish and sea anemones.

Although Cnidarians exhibit a wide variety of colors, shapes and sizes, they all share the same distinguishing characteristics; a simple stomach with a single mouth opening surrounded by stinging tentacles. The colony is formed by a process called budding, which is where the original polyp literally grows copies of itself.

Soft corals are found in oceans from the equator to the north and south poles, generally in caves or ledges. Here, they hang down in order to capture food floating by in the currents that are usually typical of these places.

Hard corals extract abundant calcium from surrounding seawater and use this to create a hardened structure for protection and growth. Inside the tissues of each coral polyp live these microscopic, single-celled algae, sharing space, gas exchange and nutrients to survive.

This symbiosis between plant and animal also contributes to the brilliant colors of coral that can be seen while diving on a reef. It is the importance of light that drives corals to compete for space on the sea floor, and so constantly pushes the limits of their physiological tolerances in a competitive environment among so many species.

Coral reefs are part of a larger ecosystem that also includes mangroves and seagrass beds. Mangroves are salt tolerant trees with submerged roots that provide nursery and breeding grounds for marine life, that then migrate to the reef.

Mangroves also trap and produce nutrients for food, stabilize the shoreline, protect the coastal zone from storms, and help filter land based pollutants from run off. Seagrasses are flowering marine plants that are a key primary producer in the food web.

During feeding a coral polyp will extend its tentacles out from its body and wave them in the water current where they encounter small fish, plankton or other food particles. The surface of each tentacle has thousands of stinging cells called cnidoblasts, and when small prey floats or swims past, the tentacles fire these stinging cells, stunning or killing the prey before passing it to the mouth.

This is where only male gametes are released into the water, then taken in by female coral animals containing egg cells. This Paula is released through the mouth of the female coral and drifts or crawls away to settle elsewhere and grow into a new colony.

Coral spawning happens at the same time each year and appears to be related to the lunar cycle. This allows scientists and divers the opportunity to observe this magnificent phenomenon, along with all the fish and predators that come to feed on them.

However, under favorable conditions (high light exposure, consistent temperature, moderate wave action), some species can grow as much as 4.5 cm per year. Temperate and tropical reefs however are formed only in a zone extending at most from 30°N to 30°S of the equator; the reef-building corals preferring to grow at depths shallower than 30 m (100 ft), or where the temperature range is between 16-32oc, and light levels are high.

They are separated from the coast by a stretch of water which can be up to several miles wide and several tens of meters deep. Sandy islands covered with a characteristic pattern of vegetation have sometimes formed on top of a barrier reef.

Like their relatives, the jellyfish and the sea anemone in the Cnidaria phylum, each individual coral, or polyp, has barbed, stinging cells called nematocysts it can extend to capture prey like zooplankton or small fish. Coral almost could be considered half-plant because of the zooxanthellae (pronounced zoo-zan-thelly) algae that live just inside each polyp's cell walls.

In turn, the polyp shelters the zooxanthellae and provides the carbon, nitrates and phosphates the algae need for photosynthesis. Up to 90 percent of the energy produced by zooxanthellae's photosynthesis is transferred to the coral host .

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.

They simply secrete more calcium carbonate under and around their current cup, creating the framework of the reef and causing it to grow both upwards and outwards. Corals may reproduce either asexually, by dividing and producing identical clones, or sexually, by sending out eggs or sperm.

In addition to being connected at their bases, coral polyps link to one another laterally by a thin tissue called the coenosarc.
