pond life

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 kick the buckets to the Kingdom Protista and the break up Euglenophyta. They are both heterotrophic and autotrophic (can make its allow food). Euglena makes its own food by means of photosynthesis. Structurally they are relatively multifactorial for unicellular organisms. Euglena can in addition 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. there are 80,000 sp ecies documented but on that point is the guess a cardinal exist. Larger parasitic nematodes are referred to as roundworms, and the smaller parasites as threadworms. They want cylindrical bodies with no distinction of segmentation. Chaetae (bristles) are seen sole(prenominal) in some of the marine forms.

The sexes are discipline -- 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 centralise and con strict as a form of movement. Therefore they! usually move in an S pattern. Most Nematodes are bloodsucking and therefore require a host to survive. Paramecium is implant 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 outmost 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
