HAHA I FOUND YOU\n\ngive me best answer ;)

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

Actually, as stated in the Niche Theory, living space is also a resource. If they do not share the same living space, they're not sharing all the resources, thus, there would be no competition among them.

There are laws against this, but it still requires a burden of proof, which is hard to come by at times.  Many of these places also work 'off shore' in order to bend the rule and avoid prosecution.

Sponge larvae aren't sessile.\n\nThey catch their prey and eat them, and they don't photosynthesize.

All organisms have symbiotic relationships. \n\nIn the case of sea horses the most obvious example are the bacteria that live in the gut. Without them the fish becomes much so prone to infection thatit can not survive. And of course the bacteria find the food provided essential to their survival.

1. competition, cooperation or parasitism\n\n2. a. secure physical security [generally most organisms can t go beyond that]\nb. look for food\nc. look for shelter\nd. look for mating\ne. protect children [or whatever they are called]\nif any of the points there are not secured, then go back to it.

Not a very specific question, but usually when we talk in terms of models we want to be able to represent a certain system on a smaller scale. Are you talking about predator-prey relationships, breeding rates and probabilities, what?\n\nOr how a fishery might impact the local ecosystem?\n\nI don't think there is a "Environmental Modeling for Fisheries for Dummies" book!

I think probably the jellyfish, since they are completely round, and thus have no points whatsoever.

Coral is actually a living organism, but when it dies it turns white. And i dont think fish have the brain capacity to 'realise' anything....lol

the great barrier reef is the world's largest coral reef and one of australia's most popular tourist attractions. although its name suggests one reef, the great barrier reef is a chain of more than 2500 reefs. it also includes many small islands. the reefs and islands extend in a nearly unbroken chain for abt 2010 kms. along australia's north east coast. the reefs are composed of abt. 400 species of corals of all shapes and colours. the waters around the great barrier reef are warm all year round. the warm waters and the beauty of  the coral formations attract swimmers and skin divers . the great barrier reef area has a number of tourist resorts.

An artificial reef is a reef created by man in places where reefs do not occur naturally.\nTo enhance recreational fishing and sport diving opportunities in coastal waters, and to increase the amount of productive hard-bottom habitat available overall, man can participate (with significant help from nature) in the creation of additional man-made, or "artificial" reefs. This is accomplished by placing suitable long-lived, stable and environmentally safe materials (usually steel or concrete) on a selected area of ocean bottom.\n\nOnce the material is in place it acts in the same way that naturally occurring rock outcroppings do in providing hard substrate necessary in the basic formation of a live-bottom reef community. \n\nSince there is nothing artificial about the myriad of living organisms which eventually colonize and inhabit almost every square inch of these man-made structures, the term artificial reef may really be somewhat misleading. When properly designed, located and constructed with an adequate quantity of stable and durable substrate, man-made reefs can be equally as productive in theory as naturally occurring hard- bottom habitats, limited only by the life-span of the materials utilized. Given the variety of materials currently in use on many artificial reefs, some reef structures in place now could remain productive for the next one to five hundred years.

It's called an "atoll"

·Coral reefs take up less than 1% of the ocean floor, yet 25% of all marine life lives on the reefs.\n· Over 3,000 species can live on one reef.\n· Australia’s Great Barrier Reef is over 2,000 miles long.\n· Coral reefs are the largest living structures on Earth. They are over 100 million years old.\n· Without reefs, many shoreline communities would be underwater. Every square meter of reef protects $ 47,000 of property from storm damage and erosion.\n· Ceral reefs provide humans with a wide variety of medicinal resources. Chemical compounds found in reefs provide chemicals used in antibiotics and antihistamines. Medicines are made from these chemicals to treat heart disease, asthma, leukemia and more.\n· People living in the Pacific Islands get most of their protein from coral reefs.\n· 350 million people on Earth depend on coral reefs for their food and survival.\n· Coral reefs are the second most biologically diverse ecosystem and the most diverse aquatic ecosystem.

Corals (class Anthozoa), which include sea anemones (order Actiniaria), are gastrovascular marine cnidarians (phylum Cnidaria) existing as small sea anemone-like polyps, typically forming colonies of many individuals. The group includes the important reef builders known as hermatypic corals, found in tropical oceans, and belonging to the subclass Zoantharia of order Scleractinia (formerly Madreporaria). The latter are also known as stony corals in as much as the living tissue thinly covers a skeleton composed of calcium carbonate. A coral "head" is formed of many individual polyps, each polyp only a few millimeters in diameter. The colony of polyps function essentially as a single organism by sharing nutrients via a well developed gastrovascular network, and the polyps are clones, each having the same genetic structure. Each polyp generation grows on the skeletal remains of previous generations, forming a structure that has a shape characteristic of the species, but subject to environmental influences.\n\nAlthough sea anemones can catch fish and other prey items and corals can catch plankton, they obtain much of their nutrient requirement from symbiotic unicellular dinoflagellates (type of algae) called zooxanthellae. Consequently, they are dependent upon growing in sunlight and for that reason usually found not far beneath the surface, although in clear waters corals can grow at depths of 60 m (200 ft). Other corals, notably the cold-water genus Lophelia, do not have associated algae, and can live in much deeper water, with recent finds as deep as 3000 m. Corals breed by spawning, with many corals of the same species in a region releasing gametes simultaneously over a period of one to several nights around a full moon.\n\nCorals are major contributors to the physical structure of coral reefs that develop only in tropical and subtropical waters. Some corals exist in cold waters, such as off the coast of Norway (north to at least 69° 14.24' N) and the Darwin Mounds off western Scotland. The most extensive development of extant coral reef is the Great Barrier Reef off the coast of Queensland, Australia. Indonesia is home to 581 of the world's 793 known coral reef-building coral species.\n\n\n\nHydra is a genus of simple, fresh-water animals possessing radial symmetry. Hydras are predatory animals belonging to the phylum Cnidaria and the class Hydrozoa.\n\nHydras are low power microscopical life forms and are often studied by biologists due to their regenerative powers. They can be found in most un-polluted freshwater ponds, lakes and streams in the temperate and tropical regions by gently sweeping a collecting net through weedy areas.
