There are 15 species of porcupine fish, but they mainly feed on coral and mollusks. A mollusk is a snail or a squid or octopus I believe. Coral are those small organisms the reefs are made out of, like a coral reef.

Lots of them in aquaculture--Fish, shellfish, shrimp, sponges...\n\nOn land, you've got bees and silkworms, and aren't there some crocodile or alligator farms?

Phytoplankton which are like plants.\nZooplankton like crustaceans which eat the phytoplankton and other small creatures.\nFish feed on small creatures and other fish.\nSquid and Octopi feed on shell fish.\nEels feed on fish.\nSharks feed on fish.\nWhales feed on small plankton.\nJellyfish feed on small fish.\nThese are all consumers in the ocean.

Probably a mutualism in which coral provides structure, support, and security, while the algae provide energy for the coral.

We can think in general terms of a food chain consisting of three main groupings, or trophic levels: plants, herbivores, and carnivores. Plants are at the "bottom" of the food chain—they are able to make their own food by using the energy from the sun (they are autotrophic). Because they produce their own food, they are called Producers. All other living things that can't make their own food must consumer the producers, so they are called consumers (and are heterotrophic). Consumers are higher up the food chain (at a higher trophic level) and are either herbivores (they directly consume the producers) or carnivores (they eat other consumers). Macroinvertebrates are heterotrophic and may be both herbivores and carnivores. \n\nBecause benthic macroinvertebrates eat and are eaten, they are smack-dab in the middle of the food chain, a position that is critical in a healthy stream ecosystem. Herbivorous stream bugs consume plants and algae (these bugs are the scrapers and shredders). \n\nThe benthic macroinvertebrates that eat small fish, small amphibians, and other stream bugs are the carnivores. These predaceous macroinvertebrates are the predators\n\nTo confuse matters slightly, there is another group in addition to the herbivores and carnnivores. Detritivores are sort of a combination of herbivores and carnivores. Detritivores shred and eat leaves and other organic matter that contain nourishing fungi, algae, and bacteria. They absorb the nutrients as they break down the material into smaller sizes that other bugs utilize. Detritivores are the shredders and collectors. \n\nStream bugs may get eaten by other macroinvertebrates and fish that depend upon them for food. For example, both juvenile and adult salmon eat macroinvertebrates. And not only do other consumers need them for food, but when the bugs die, they decay and leave nutrients behind that flow back into the food chain. \n\nSo without the stream bugs, organic materials won't be processed, nutrients won't get recycled back into the system, and many consumers won't have any food—in short, the system degrades until it is unhealthy or dead, then most bugs couldn't live there even if they wanted to.

Usually they are scavenging feeders but to be specific they eat certain types of fish, crusteans and mollusks such as octopuses, squids and crabs\n\nhttp://www.sea-ex.com/fishphotos/flathead.htm

1. Coral reefs:\nThere are many types of algae that live inside and outside corals. \nMainly Caulerpa and Corallina species, and many more are named there:\nhttp://www.com.univ-mrs.fr/IRD/atollpol/ecorecat/ukalgrec.htm\n\nInside coral polyps themselves, there are symbiotic microscopic algae. Their common name is "zooxanthellae", but they are in fact multiple species of Dinoflagellata:\nhttp://www.marinebiology.org/coralbleaching.htm\n\n2. Tropical algae: again, far too many to list.\nLook around the Seaweed Site, and pick ones that grow in tropics. http://www.seaweed.ie/\n\n3. Besides algae, there are seagrasses (flowering plants living in the ocean):\nhttp://en.wikipedia.org/wiki/Seagrass

Both food chains and food webs are ecological models, that is, simplified representations of some aspects of an ecosystem. \nIn the case of a food chain, it's a schematic representation of the "eats/is eaten by" relationship; really simple and unidimensional. Each trophic level is occupied by one species, and arrows indicate who eats who. \nThis is a diagram of a simple food chain:\nhttp://www.ddc2000.com/products/samples/s2kwebdemo/support/data/unit00/06images/2502.jpg\n\nHowever, in most ecosystems there are many different species in each trophic level, and many organisms that may occupy different levels (for instance an omnivorous animal can be both a first order and second order consumer). Thus, the food web is a more complex model, usually a better approximation to reality, in which many arrows go from and to each component. \nA food web looks like this:\nhttp://www.agen.ufl.edu/~chyn/age2062/lect/lect_28/40_07.GIF\n\nMore complicated, but the same type of model that only shows trophic (alimentary) relationships.

Yes, if it is an organic reef. However, contrary to the other answer, reefs are built by many liviing organisms, not just corals (cnidarians), and most coral reefs have a large number of other organisms that contribute significantly to building the reef. Modern coral reefs are composed of 40-80% coral, with the other primary component being calcareous algae. In some instances calcareous algae compose almost all of the reef. Many other organisms inhabit the reef and contribute to its build-up such as bryozoans, encrusting molluscs, and even microbes which often cement particles together. Other types of organisms do build reefs too. Oysters build reefs in some modern oceans.\nhttp://www.sms.si.edu/IRLspec/Oyster_reef.htm\n\nIn geologic history organic reefs have been built by a much more varied group of organisms. In the Cretaceous large bivalves known as rudists built reefs. In the Permian large reefs such as the Guadelupe Escarpment where Carlsbad Caverns is located were built by bryozoans, calcisponges, and microbes.  In the Pennsylvanian algal colonies known as phylloid algae built bioherms that resembled reefs. In the Devonian stromatoporoids built reefs, and archaeocyathids build reefs way back in the Cambrian. \n\nHowever, not all reefs are organic. Many reefs, also called shoals, are simply shallow rock or piles of sediment that rise nearly to the surface of the ocean.

Food chains follow a single path taken as different creatures eat each other for energy.\nA food web is a formation of interconnected food chains.It explores how ALL life is connected.It is not a single path like a food chain is.

There are a whole lot of apples and oranges mixing up here.\n\nThe Great Barrier Reef off Queensland is an ecosystem made up of many thousands of species of organisms. As an ecosystem, it's been accreting more or less continuously for a long time (since probably the Cretaceous Period). But during that long time the species of reef builders (corals and algae) have changed.\n\nThe modern stromatolite example is from Shark Bay, Western Australia. These stromatolites look very much like Precambrian ones. They are made of/by blue-green algae (cyanobacteria). So while the stromatolites could be considered an example of a type of ecosystem that hasn't changed for 600+ million years, the individual algal organisms themselves only live for a few days or weeks.\n\nSo the Bristlecone Pine is the oldest living single organism.

Hermatypic corals (the ones that form coral reefs) have symbiotic zooxanthellae (unicellular algae) within their tissues; the algae receive protection and housing from the polyps, and enable them to produce their calcareous exoskeleton.\nThere are sea anemones that attach to the dorsum of crabs, marine snails, etc. Thus the anemone "travels free" and the other animal is protected. \nMany species of small fishes and crustaceans shelter beneath the umbella of some jellyfish (read example at the link).

Feeding Habits - Warmouths are carnivorous. Crayfish, shrimp, insects and small fishes make up the bulk of its diet. Most of its feeding is done in the morning, as it seems to sleep at night.
