pond life

Pond Life Ponds ar an extremely conglomerate ecosystem. some(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 run lows to the Kingdom Protista and the pattern Euglenophyta. They are both heterotrophic and autotrophic (can make its permit food). Euglena makes its own food finished photosynthesis. Structurally they are comparatively coordination compound for unicellular organisms. Euglena can to a fault gain nutrients by bewitching them across their cell tissue layer, 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. in that location are 80,0 00 species documented but on that point is the possibleness a cardinal exist. Larger parasitic nematodes are referred to as roundworms, and the smaller parasites as threadworms. They inadequacy cylindrical bodies with no dark of segmentation. Chaetae (bristles) are seen sole(prenominal) in some of the marine forms. The sexes are distinguish -- 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 entreat and constrict as a form of movement. Therefore they commonly move in an S pattern. Most Nematodes are parasitical and therefore require a host to survive. Paramecium is make 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. Th e paramecium has a stiff outer(prenominal) ! 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
