This biome is usually divided into two categories: freshwater and marine. Typically, freshwater habitats are less than 1 percent salt and includes: ponds, lakes, rivers, streams, wetlands and estuaries. Marine life, however, has to be adapted to living in a habitat with a high concentration of salt. Marine habitats include the ocean and salty seas and are often subdivided further into zones or real

Freshwater ecosystems include the littoral, limnetic, and profundal zones in lakes, each supporting different life forms and productivity levels. Seasonal changes lead to oxygen mixing in these zones. Rivers and streams typically have higher oxygen levels and rely less on photosynthesis, while oceans have similar zones but different naming conventions.

(Note that this term can also refer to artificial lakes created by dams.) Water is found as a liquid on the surface (rivers, lakes, oceans) and beneath the surface (groundwater), as ice (polar ice caps and glaciers), and as water vapor in the atmosphere.

Water is found as a liquid on the surface (rivers, lakes, oceans) and beneath the surface (groundwater), as ice (polar ice caps and glaciers), and as water vapor in the atmosphere. Water reservoirs are the locations where water is stored. The hydrologic cycle describes how water moves around the world between different reservoirs and forms.

The aquatic medium—water— has different physical and chemical properties than air, however. Even if the water in a pond or other body of water is perfectly clear (there are no suspended particles), water, on its own, absorbs light. As one descends into a deep body of water, there will eventually be a depth which the sunlight cannot reach.
