Pond Life Ponds ar an extremely conglomerate ecosystem. several(prenominal) of the many a(prenominal) organisms you will find in it argon Nematodes, Euglena, Paramecium, genus Volvox and rotifers. These organisms may be tiny but they play a life-sustaining role in their ecosystem. Euglena pop offs to the Kingdom Protista and the yr Euglenophyta. They are both heterotrophic and autotrophic (can make its permit food). Euglena makes its own food by photosynthesis. Structurally they are relatively labyrinthine for unicellular organisms. Euglena can also gain nutrients by bewitching them across their cell membrane, hence they become heterotrophic when clean is not available, and they cannot photosynthesize. Euglena move by a flagellum. They also fill a stiff pellicle outside the cell membrane to charge in maintaining their shape. Nematodes are frequently described as likely the most numerous animals on Earth. at that place are 80,000 species documented but on t hat point is the opening move a cardinal exist. Larger parasitic nematodes are referred to as roundworms, and the smaller parasites as threadworms. They deficiency cylindrical bodies with no wind of segmentation. Chaetae (bristles) are seen sole(prenominal) in some of the marine forms.
The sexes are wear -- there is no hermaphroditism in the nematodes, but in definite species the females at certain stages reproduce parthenogenetically. They have no bank line system, no respiratory system and no cilia. They also have no circular muscle, which makes them unable to start and constrict as a form of movement. T herefore they ordinarily move in an S patte! rn. Most Nematodes are leechlike and therefore require a host to survive. Paramecium is build in freshwater throughout the world. Like other protozoa, paramecia, belong to the state kingdom Protista. Paramecia and other ciliates is the most complex of all one-celled organisms. The paramecium has a stiff outermost covering that gives it a permanent oval shape. It moves swiftly through the water by coordinated wavelike beats of its...If you want to get a full essay, order it on our website: OrderCustomPaper.com
