Marshland is covered with grasses, reeds, sedges, and cattails. These plants all have their roots in soil covered or saturated with water and its leaves held above water. Marshes may be freshwater or salt. Freshwater marshes develop along the shallow edges of lakes and slow-moving rivers, forming when ponds and lakes become filled with sediment.
In other words, a biome refers to the group of organisms restricted by the environment to a particular climatic zone. No biome is exclusively restricted to one locality; however, examples of the same biome in widely remote areas are usually made up of different component species of plants and animals.
The biomes often merge with no clearly defined border, and it is sometime difficult to say precisely where one biome ends and another begins. Boundary areas, however, do have distinctive plant communities, and animals from neighbouring biomes can wander in and out of them.
Generally, however, aquatic biomes can be exemplified by: The horizontal sequential distribution of the major biomes from the pole to the equator corresponds, remarkably with the sequence of similar biomes from the higher peaks of certain mountains to the sea level.
However, in some biomes, e. The tropical forest biome has the greatest abundance and density of species. About 10 million species are estimated to exist on earth and of these about 5 million occur in this biome alone see Myers, This biome is also the least explored one and is now being increasingly subjected to various stresses of disruption and destruction.
This could lead to extinction of thousands of species. Organisms that live in water have to face certain osmotic problems and have developed osmoregulatory devices or organs. Even though the basic principles of ecosystem relations are the same for terrestrial and aquatic habitats, the communities of living things in a stream or lake are decidedly different from those on land.
As on land, in aquatic communities too it is the plants that form the basic component of the ecological link. However, the more uniform aquatic habitats, especially oceans, have somewhat less varied distributions of various kinds of plant communities.
Highly distinctive kinds of ecosystems are characteristic of salt lakes, marshes, and subterranean environments.
Various algae are the predominant plants of aquatic ecosystems. Seaweeds marine members of green, brown, and red algae form the major element of sublittoral and littoral coastal vegetation.
Freshwater communities of shallow waters include many aquatic angiosperms e. The oceans constitute the most extensive and the largest abodes of life. Marine biota include species from all the animal phyla and from all except two Bryophyta and Tracheophyta of the plant phyla.
However, in many marine communities, insects are generally absent though secondarily marine insects may occur but various crustaceans such as copepods, ostracods, amphipods, and small shrimps, prawns are common. Unlike freshwater, the Ocean contain many sessile organisms such as sponges, corals and seaanemones.
Marine plankton mostly includes diatoms and dinoflagellates, Foraminifera and Radiolaria. In the oceans, the nektonic animals swimming forms are mostly carnivorous, e.A biome is a large, distinctive, complex community of plants and animals in a region maintained by climate.
There are different types of biomes including tundra, taiga, deciduous forest, scrub forest, grasslands, desert and rain forest.
