Water Biomes

Water Biomes

Marshland is cover with grasses, reeds, sedges, and cattails. These plants all have their

roots in soil covered or saturated with irrigate and its leaves held above water.Marshes may

be freshwater or sodium chloride. freshwater marshes develop along the shal humiliated edges of lakes and

slow-moving rivers, forming when ponds and lakes become fill with sediment. common salt

marshes occur on coastal tidal flats. Inland salt marshes occupy the edges of lakes. They

affect the supply of nutrients, the movement of water, and the type and deposition of

sediment.

        Salt marshes ar best developed on the Atlantic coasts of due north America and

Europe. In eastern North America the low marsh is dominated by a single species, salt-

marsh cordgrass. The luxuriously marsh consists of a short cordgrass called hay, spike grass, and

glasswort. glasswort is the dominant plant of Pacific Coast salt marshes.

        Freshwater marshes provide nesting and wintering habitats for waterfowl and

shorebirds, muskrats, frogs, and many aquatic insects. Salt marshes are wintering

grounds for snow geese and ducks, a nesting habitat for herons and rails, and a source of

nutrients for estuarial waters. Marshes are important in flood control, in sustaining high-

water tables, and as settling basins to reduce pollution downstream. Despite their great

environmental value, marshes are continually being destroyed by drainage and filling.

        Marine Life, plants and animals of the sea, from the high-tide check into along the

shore to the depths of the ocean. These organisms fall into three major groups: the

benthos, plants such as kelp and animals such as brittle stars that live on or depend on the

bottom; the nekton, swimming animals such as fishes and whales that move

independently of water currents; and plankton, various small to microscopic organisms

that are carried along by the currents.

        Shore Life, the essentially marine organisms...
