whats the ecological importance of the phylum rhizopoda?

Varied like any one cell organism. Amoeba are in this class. They process varied organic matter so they serve a recycling function. More info at the links given.

You may be thinking of homeobox genes. These genes are crucial to early development and have been greatly conserved between groups of organisms. The genes tell the embryo what the basic body plan is. If there's a homebox mutation, you may end up with three arms or a leg where an arm goes, etc. These genes are very important but they aren't the only ones and I'm not sure you could say that any genes are "dedicated to protecting the substance of each biological life form."

Plankton are drifting organisms that inhabit the water column of oceans, seas, and bodies of fresh water.\n\nAmoeba itself is found in freshwater, typically on decaying vegetation from streams, but is not especially common in nature. However, because of the ease with which they may be obtained and kept in the lab, they are common objects of study, both as representative protozoa and to demonstrate cell structure and function. The cells have several lobose pseudopods, with one large tubular pseudopod at the anterior and several secondary ones branching to the sides. The most famous species, A. proteus, is 700-800 μm in length, but many others are much smaller. Each has a single nucleus, and a simple contractile vacuole which maintains its osmotic pressure, as its most recognizable features.

Microorganisms (soil bacteria) are the most important component of any soil. They dissolve rock particles and release nutrients to the plants through decomposition. The microorganisms release carbon dioxide gas into the film of water surrounding soil particles, making the water slightly acid. This causes it to react with the rock particles and dissolve them, providing a slow, steady release of nutrients.\n\nAll microorganisms decompose decayed vegetation or other microorganisms. The decayed vegetation, called humus, is the basis for soil life. Without humus, we get no naturally formed nitrogen, and plants become weak and more susceptible to insect attack. Humus has other beneficial effects besides feeding soil microorganisms. It mechanically loosens the soil itself and creates a texture called good tilth.\n\nWhen soil has good tilth, it is soft, porous and easy to work and crumbles easily into fine pieces. Water penetrates the soil better and the soil also holds more water.\n\nTilth prevents the formation of hard crusts on the soil's surface. It allows plants to put out larger root systems easily. When there is lots of air in the soil, microorganisms flourish and speed mineral release. Good tilth allows delicate seedlings to get a good start. Focusing on the basics: \n\nAbundant Soil Microorganisms \nImproving Humus and Tilth \nis the first step and the foundation for long-lived successful reclamation, and restoration of the soil ecosystem.

An invertebrate is any animal without a backbone. Invertebrates make up 95% of all species of\nanimals on the earth, and the variety of invertebrates is enormous. Scientists group or “clas\nsify” all of these different types of animals into broad categories called phyla, on the basis of\ntheir patterns of symmetry and on the basis of their overall body plan. There are 5 particularly important\ninvertebrate phyla (and another 23 or so less important phyla). The major invertebrate groups are classified as:\n· Phylum Cnidaria: sea anemones, corals, and jellyfish\n· Phylum Annelida: segmented worms\n· Phylum Mollusca: clams, snails, and squids\n· Phylum Arthropoda: lobsters, beetles, crabs, and flies and scorpions\n· Phylum Echinodermata: sea urchins, sea cucumbers, and starfish\n\nsee more info at:http://www.msc.ucla.edu/oceanglobe/pdf/Invertebrates/Inverts_Entire.pdf\n\nI hope this helps...\n\nDon

well, it definitely sounds like an arthropod, so the place to look would be a book or website with lots of pictures of different kinds of Arthropods - crustaceans, spiders, centipedes, insects, and more, they're all in the phylum Arthropoda.  Your arthropod sounds like it's in one of the lesser known groups.

It is not E because fungi are not photosynthetic, therefore I would say 'B' is false.  I would say 'C' as it is typically taught that bacteria symbiotically fix nitrogen for plants not fungi.  The fungi that live in symbiosis with plant roots (ie mycorrhizas) typically help the plant absorb nutrients from the soil.

Zoomastigina is sometimes considered a Phylum of Protozoan unicellular critters.\n\nThey are generally flagellate critters that do not photosynthesize.\n\nThat's about all I know, sorry.

First, I am not a scientist but a scientfic researcher. It's important to know what animals eat the seeds or fruits of flowering trees to deduce it's role in a given ecosystem. It's relationship to the other living organisms in it's environment is very important. It's also imortant to know what animals very existence hinges on the trees continued existence in the ecosytem. In other words, as trees get chopped down and various animal species that depend on the trees start to die, that is then a useful barometer of the trees role in the ecosystem.

Salaginella, Isoetes, Psilotum, Lepidodendron, Paurodendron, Equisetum, Pleuromeia, Nathorstiana, Phylloglossum, Tmesipteris, Pertica, Zosterophyllum, Psilophyton, Sawdonia, Horneophyton, Crooksonia, Rhynia, Aglaophyton, Onoclea, Todea, Osmunda\n\nMany of these are extinct.\n\nDon't listen to the first answer; fungi are not plants.\n\nGlad to see more people taking an interest in these things.\nThere is also a great book called "Primitive Land Plants," by F.O. Bower.

they are evolutionary distinct!\narchae dont have a peptidoglycan cell wall.\nmoreover they live in extreme conditions such as high temp springs and very low pH!
