BIOME : 

BIOME A biome is a large group of ecosystems with similar climates and organisms Grouping ecosystems into biomes helps ecologists describe the world

BIOME : 

BIOME Water Biome Land Biome

WATER BIOME : 

WATER BIOME About three quarters of the earth's surface is covered with water The water biome is divided into freshwater (water with little salt in it, in ponds, rivers, streams) and marine, or salt water (ocean) ESTUARY

SALTWATER : 

SALTWATER water biome that has high salt content divided into three zones shallow ocean zone ocean surface zone Deep ocean zone

SALTWATER : 

SALTWATER marine or saltwater regions cover about three-fourths of the Earth's surface marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide the evaporation of the seawater provides rainwater for the land

FRESHWATER : 

FRESHWATER have a low salt content plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean)

ESTUARY : 

ESTUARY Areas where freshwater streams or rivers merge with the ocean This mixing of waters with such different salt concentrations creates a very interesting and unique ecosystem

ESTUARY : 

ESTUARY Microflora like algae, and macroflora, such as seaweeds, marsh grasses, and mangrove trees (only in the tropics), can be found here Estuaries support a diverse fauna, including a variety of worms, oysters, crabs, and waterfowl
