Also, are Volvox and  Radiolarians autotrophs or heterotrophs?

Most members of that kingdom are unicellular, but some are colonial and there are some that a simple multicellular.\n\nVolvox is a green alga and makes its own food, so it is an autotroph.  Radiolaria are heterotrophs.

Your question is vague and / or incomplete.Still I will do my best to answer it.\n Planktons = Planktons are microscopic aquatic organisms that float and drift on the water surface. Mostly are single celled but need not be always.The size matters and it has to be microscopic.\nThese planktons are of two main types i) Phytoplanktons and ii) Zooplanktons.\ni)Phytoplanktons-: Basically these are planktons as mentioned above as they fit in to that category.In addition, they have chloroplasts with chlorophyll. So they can prepare their own food like all plants that we know.Therefore the prefix PHYTO- is put before them to indicate their plant like character and affinity with the Plant Kingdom.\nMany unicellular algae come in this group.They are found in the seas as well as fresh water.Diatoms Volvox Chlamydomonas Eudorina Pandorina are but a few examples.\nii) Zooplanktons-:Basically these are planktons as mentioned above as they fit in to that category.But they do not have  chloroplsts like the first one and hence they cannot prepare their own food.Thus they are more animal like in their nutrition and hence the prefix ZOO- is put before them to indicate their animal like character and affinity towards the Animal Kingdom.These are also found in sea and fresh water.Many protozoa and larvae of aquatic animals come in the category.\nHuge animal like Baleen Whale largy depend upon this planktonic flora and fauna for their subsistance.\n Now in the light of the above information kindly rephrase your question. Your personal information will have no bearing on the answer so you need not give it.

"No protists are producers."\n\nI'm sure of it. Protists are the "junk drawer" of kingdoms.\nThe category of Protists includes many widely ranging microbes, including slime molds, protozoa and primitive algae. They are all eukaryotic <you-carry-ah-tick> creatures, meaning their DNA is enclosed in a nucleus inside the cell (unlike bacteria, which are prokaryotic <pro-carry-ah-tick> and have no nucleus to enclose their DNA. \n\nAlgae, Protozoa, Slime molds: Some produce and some consume.

(m)\n\nPlanaria sp. is a common freshwater, non-parasitic member of the phylum Platyhelminthes, class Turbellaria. It should be noted that the term "planaria" is most often used as a common name, much in the same way as trout. It is also the name of a genus within the family Planariidae. It moves by beating cilia on the ventral dermis, allowing it to glide along on a film of mucus. Some move by undulations of the whole body by the contractions of muscles built into the body wall. They exhibit an extraordinary ability to regenerate lost body parts. For example, a Planaria split length wise or crosswise will regenerate into 2 separate individuals. The size ranges from 3 to 12mm, and the body has two eye-spots (also known as ocelli) that can detect the intensity of light. The eye-spots act as photoreceptors and are used to move away from light sources. Planaria have 3 germ layers (ectoderm, mesoderm, and endoderm), but lack a body cavity or coelom. They have a single-opening digestive tract, consisting of one anterior branch and two posterior branches in freshwater planarians. Because of this three-branched organization, freshwater flatworms are often referred to as triclad planarians.\n\nPlanaria are common to many parts of the world and reside in fresh water ponds and rivers. They are also commonly found residing on plants.\n\nThe most frequently used in the high school and first-year college laboratories is the brownish Dugesia tigrina. Other common varieties are the blackish Planaria maculata and Planaria dorotocephala. Recently, however, the species Schmidtea mediterranea has emerged as the species of choice for modern molecular biological and genomic research due to its diploid chromosomes and existence in both asexual and sexual strains. Recent genetic screens utilizing double-stranded RNA technology have uncovered 240 genes that affect regeneration in S. mediterranea. Intrerestingly, many of these genes are found in the human genome

They are called Carnivorous Plants.The following genera are treated as being carnivorous here: Aldrovanda, Byblis, Cephalotus, Darlingtonia, Dionaea, Drosera, Drosophyllum, Genlisea, Heliamphora, Nepenthes, Pinguicula, Sarracenia, Triphyophyllum and Utricularia. \n\nSeveral members of the Bromeliaceous genera (Brocchinia and Catopsis), along with the "devil's claw family" ( Craniolaria, Ibicella, Martynia, and Proboscidea ) and others are considered carnivores (or possible carnivores)

You probably mean phytoplankton.\nThere are several types.  See the wikipedia article referenced below.

Some algae are motile. Single-celled algae often have flagellae and move in a spiralling manner. Others do not have flagellae but secrete a sticky substance which attach them to the substrate, enabling them to glide along leaving a trail of slime behind.\n\nSome Diatoms (pythoplankton) can also move on their own thanks to their flagellae.  Then there's the rhodophyta and the cyanobacteria, which are not exactly plants but will also enlighten your way to finding what you need.\n\nOtherwise, plant cells are not moile.

these are called the classical "work horses" of plant and aniamal cells respectivly.  Regardless chlorplast is reposnsible the energy conversionin photsysnthesis and mitochondia is used in cell metabolism to provide energy through ATP-ADP energy relationships. Any basic science book would do this and so would a Wikepedia or googlesearch. I woudl suggest you go there to get spsecifics, or try the library in your neighbourhood

it is a hermaphrodite...this also occurs in many invertebrates including flatworms and some earthworms.  \n\nremember that a hermaphrodite does not mean that it mates with itself spontaneously, though.  it still needs a mate, but it can serve as either a male or female since it has both sets of reproductive organs.

Life? Sure. Given the speed at which bacterial life formed on earth after it had cooled down enough, it seems that life itself is relatively easy to get going and so would be common in the universe.\n\nOn the other hand, even on earth, it took a long time for life to become multi-cellular. Out of about 3.8 billion years that life has been around, it was one-celled for about 3.1 billion years. This suggests that multi-cellular organisms are fairly hard to get going and so are relatively rare.\n\nAs for other *intelligent* life, I think it is rather uncommon. First, is the issue of how long a species lasts once it gets to radio technology (say). Given our own experience, it may be as little as a few hundred to a thousand years. If that is the case, the probabilities of time overlap with other intelligent life becomes fairly small considering the overall age of the universe and speed of the processes in it.\n\nOne basic fact that we have to come to grips with is that other life is not *obviously* seen around us. Given likely expansion rates and rates of technological developement, we would probably become obvious before too much longer (a few thousand years): we would send self-replicating probes into the universe, or do LARGE scale projects (solar system size). Since we don't see this in the universe at large, technologies reaching that level are almost certainly rare. I would be very surprised if there is currently another species with our level of technology or higher in our galaxy.\n\nHowever, the universe is a BIG place. There are a hundred billion galaxies in the observable universe, each with an average of a hundred billion stars. Even if we only look at spiral galaxies (ellipticals have the wrong composition for our form of life, at least), there are enough of them to almost assure at least one highly advanced technology somewhere. However, the distances involved are such that we may never be able to detect them, especially if we die off in a few thousand years).

http://en.wikipedia.org/wiki/Parelaphostrongylus_tenuis\n\nMorphology\n\nRoundworms are triploblastic protostomes with a complete digestive system. Roundworms have no circulatory or respiratory systems so they use diffusion to breathe and for circulation of substances around their body. They are thin and are round in cross section, though they are actually bilaterally symmetric. Nematodes are one of the simplest animal groups to have a complete digestive system, with a separate orifice for food intake and waste excretion, a pattern followed by all subsequent, more complex animals. The body cavity is a pseudocoel (persistent blastula), which lacks the muscles of coelomate animals used to force food down the digestive tract. Nematodes thus depend on internal/external pressures and body movement to move food through their digestive tracts. The mouth is often surrounded by various flaps or projections used in feeding and sensation. The portion of the body past the anus or cloaca is called the "tail." The epidermis secretes a layered cuticle made of keratin that protects the body from drying out, from digestive juices, or from other harsh environments, as well as in some forms sporting projections such as cilia that aid in locomotion. Although this cuticle allows movement and shape changes via a hydrostatic skeletal system, it is very inelastic so does not allow the volume of the worm to increase. Therefore, as the worm grows, it has to moult and form new cuticles. The cuticles don't allow volume to increase so as to keep hydrostatic pressure inside the organism very high. For this reason, the roundworms do not possess circular muscles (just longitudinal ones) as they're not required. This hydrostatic pressure is the reason the roundworms are round.\nMost free-living nematodes are microscopic, though a few parasitic forms can grow to several meters in length. There are no circular muscles, so the body can only undulate from side to side. Contact with solid objects is necessary for locomotion; its thrashing motions vary from mostly to completely ineffective at swimming.\nRoundworms generally eat bacteria, algae, fungi and protozoans, although some are filter feeders. Excretion is through a separate excretory pore.\nReproduction is usually sexual. Males are usually smaller than females (often very much smaller) and often have a characteristically bent tail for holding the female for copulation. During copulation, one or more chitinized spicules move out of the cloaca and are inserted into genital pore of the female. Amoeboid sperm crawl along the spicule into the female worm.\nEggs may be embryonated or unembryonated when passed by the female, meaning that their fertilized eggs may not yet be developed. In free-living roundworms, the eggs hatch into larva, which eventually grow into adults; in parasitic roundworms, the life cycle is often much more complicated.\nRoundworms have a simple nervous system, with a main nerve cord running along the ventral side. Sensory structures at the anterior end are called amphids, while sensory structures at the posterior end are called phasmids.\n\nhttp://en.wikipedia.org/wiki/Nematode\n\n\nHope that helps!
