Water is the common link among the five biomes and it makes up the largest part of the biosphere. Water covers nearly 75% of the Earth’s surface. Aquatic regions are homes to many species of plants and animals. Aquatic areas tend to be more humid and a cool air temperature.

Freshwater Regions
-Freshwater is when there is a low salt concentration—less than 1%
-There are different types of freshwater regions such as ponds and lakes, streams and rivers, and wetlands
-Ponds and Lakes= limited species diversity Lakes and ponds are divided into three different “zones” which are usually determined by depth and distance from the shoreline.
-Streams and Rivers=are bodies of flowing water moving in one direction.
-Wetlands=  Wetlands are areas of standing water that support aquatic plants. Marshes, swamps, and bogs are all considered wetlands.

Marine Regions
-Marine regions cover about three-fourths of the Earth’s surface and include oceans, coral reefs, and estuaries
-Oceans are the largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth’s surface.
They have four zones: intertidal, pelagic, abyssal, and benthic.
-Intertidal is where the ocean and land meet. Pelagic is the open ocean. Benthic is below the pelagic zone, but not the deep parts. Abyssal zone is the deep ocean.
-Coral reefs are widely distributed in warm shallow waters.
-Estuaries are areas where freshwater streams or rivers merge with the ocean.
