I know this is in the wrong category, but please?

I know this is in the wrong category, but the question I posted before isn't getting alot of answers, so here it goes...

What organisms live in coral reefs?

I need one from every kingdom.

Animal? Plant? Protist? Fungi? A prokaryote?

Update:

This is only the research part of my homework, "Captain Shannon".

    *** Animal - Sponges (Porifera)

    Brachiopods (resembles clams but much more ancient)

    Arthropods (organisms with jointed legs and hard shells, including lobsters, crabs, shrimp)

    Echinoderms (organisms with 5-fold symmetry such as starfish, sea urchins, sand dollars)

    Mollusks (organisms with a mantle including the octopus, squid, snails, and clams)

    ***Plant -algae (the primitive red, brown, and green algae)

    ***Protist -diatoms, forams, coccolithophores.

    ***Fungi - mushrooms and mold.? rare sea floor...

    ***Prokaryote - Bacteria and blue-green algae (cyanobacteria) are Monerans.

    From:

    Lists 5 kingdoms and specifics.. then where they live.

    http://www.geo.umn.edu/courses/1006/Fall00_night/C...

    5 Kingdoms

    I. Monera (Prokaryotes) Simple, single-celled organisms that have no nucleus. Bacteria and blue-green algae (cyanobacteria) are Monerans.

    Bacteria are the organisms that decompose dead plants and animals and release the nutrients back into the water column.

    Blue-green algae (Phylum Cyanophyta) are significant for several reasons:

    1. They convert nitrogen into nitrate, which is the nutrient form that plants use. One of the many reactions involved in decay is:

    NH3 + 2O2 --> H+ + NO3- + H2O

    Remember that nitrate (NO3- ) is the nutrient that all plant-like organisms need to build organic matter. Plants are not capable of breaking the bonds in N2 gas. Ammonia is a common component of urine, and bacteria convert it into nitrate, which plants can then take out of seawater.

    2. Blue-green algae help cement carbonate fragments of coral reefs into hard rock

    3. These earliest photosynthetic life forms were likely responsible for releasing O2 into the Earth's early atmosphere.

    II. Protista

    The single-celled organisms that possess a nucleus. This includes both plants and animals such as: diatoms, forams, coccolithophores. They are motile and non-motile. Despite their small size they make up a large part of the living mass of the ocean, and many form the basis of food webs.

    Plant-like protists = algae (diatoms, dinoflagellates)

    Animal-like protists = protozoans (foraminifera, radiolarians)

    III. Fungi

    Fungi are multi-celled, heterotrophic decomposers. They have limited cell specialization.

    Marine fungi are not as diverse or as well studied as their terrestrial-counterparts. They are more common in the intertidal zone than in the open ocean.

    Examples include mushrooms and mold.

    IV. Metaphyta

    Multicelled plants. In the ocean these are the plants that attach to the sea floor. These are 3 phyla of algae (the primitive red, brown, and green algae), and the flowering seed-bearing plants of salt-marshes and mangrove swamps (the subject of lab this week). They are confined to shallow water of the shoreline and inner continental shelf.

    Fascinating facts

    Kelp are a type of brown algae

    The Red Sea gets it red coloring from red algae.

    Some green algae have calcite skeletons that allow them to stand up, and they are sometimes mistaken for corals.

    V. Metazoa

    These are the multicelled animals. This group is very diverse, containing more than a dozen Phyla.

    In the fossil display cases in Pillsbury Hall you can see examples of

    Sponges (Porifera)

    Extinct forms of corals (Cnidaria - organisms with stinging cells)

    Brachiopods (resembles clams but much more ancient)

    Arthropods (organisms with jointed legs and hard shells, including lobsters, crabs, shrimp)

    Echinoderms (organisms with 5-fold symmetry such as starfish, sea urchins, sand dollars)

    Mollusks (organisms with a mantle including the octopus, squid, snails, and clams)

    Chordates (organisms with a notochord, all the fish and marine mammals are here)

    Classification by Lifestyle

    A more informal way to categorize marine biota is according to lifestyle.

    PLANKTON: organisms that drift with the currents. They possess very weak swimming ability or no swimming ability at all.

    Those that can move mainly do so for vertical migration. Plankton range in size from microscopic diatoms to the large jellyfish.

    PHYTOPLANKTON: plant-like organisms (diatoms)

    Phytplankton are autotrophic. They feed themselves by photosynthesis. Phytoplankton includes diatoms, dinoflagellates, coccolithophores, silicoflagellates, green algae, blue-green algae, etc.

    ZOOPLANKTON: animals (forams, krill, etc.)

    This is an umbrella term referring to the organisms that feed on phytoplankton. It is an ecological term, NOT a classification term. Every animal phylum is found among the zooplankton.

    This group includes small crustaceans such as copepods (shrimp), euphasids (krill) amphipods. These are herbivores and consume more than half their body weight each day.

    Many of them can swim, but they still only centimeters in size, so they are still at the mercy of currents, both vertical and horizontal. By ingesting phytoplankton and creating fecal pellets, these guys are enabling nutrients to be recycled. Zooplankton follow their food source. So they like to be in areas with abundant phytoplankton, and they in turn attract predators. You find these guys in upwelling zones but also in zones of convergence, which might be surprising. At convergence zones you have 2 water masses colliding, such as at the Gulf Stream and the Labrador Current. The cold Labrador Current carries phytoplankton from the highly productive polar seas down to lower latitudes. When it hits warm Gulf Stream, the denser Labrador current is forced to downwell, taking all those plankton with it. That is a feast for the zooplankton and a huge hint for some you out there! Some areas are twice blessed with coastal upwelling and convergence.

    NEKTON: active swimmers such as fish, squid, birds, reptiles (turtles), mammals.

    Although they possess muscles for locomotion, many have their range restricted by temperature or salinity. (Animals).

    BENTHOS: organisms that are attached to, live on, or burrow under the seafloor. Includes both

    plants and animals. Plants such as seaweed need light, and are restricted to shallow coastal water. Organisms such as worms can live anywhere, even in the deepsea trenches.

    Some life forms move from one group to the other over the course of their lives. You saw in the video "Life at the Edge of the Sea" that some organisms have a larval stage that are drifters or swimmers. But the adult form is benthic. Barnacles for example, released their young to be dispersed by the currents. The ones with planktic or nekton larvae reproduced at Spring Tides, so that their young were dispersed with the currents. In contrast herring needed quiet water to lay eggs in the sea grass.

    animal ~ a cat ( shocker, right )

    plant ~ tulip ( even MORE of a shocker )

    fungi ~ yeast or mildew

    and yeah, i dont listen to the teacher very much.
