Seagrass cell walls contain the same polysaccharides found in angiosperm land plants, such as cellulose [103] However, the cell walls of some seagrasses are characterised by sulfated polysaccharides, [104] [105] which is a common attribute of macroalgae from the groups of red, brown and also green algae.
Spartina alterniflora (), a halophyte.. A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores.
About 0.085% of the 300,000 Angiosperms believed to exist can be found in marine like environments. [1] Some examples of what plants in this kingdom exist are mosses, ferns, seagrasses, mangroves, and salt marsh plants—the last three being the three major communities of angiosperms in marine waters.
Given the wide variety of food sources provided by this productive habitat, it is no surprise that seagrass meadows support an equally wide array of grazers and predators. However, despite its importance for sustaining biodiversity and many other ecosystem services, [ 16 ] the global distribution of seagrass is a fraction of what was ...
This is typically found where rivers meet the ocean or sea. The wildlife found within estuaries is unique as the water in these areas is brackish - a mix of freshwater flowing to the ocean and salty seawater. [16] Other types of estuaries also exist and have similar characteristics as traditional brackish estuaries. The Great Lakes are a prime ...
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [ 28 ] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
