Thursday - October 11, 2018 10:45 am , Category : Fun Facts

WTN- The marine biomes include tidal estuaries , coral reefs, and ocean  about three quarters of the planet in total ,a dynamic system that is vital to sustaining the rest of Earth’s life –forms .Oceans represent the largest portion of this biome by far and are divided  into three zones. Pelagic , commonly called the open sea, extending to about 13,000 feet below sea level: benthic , the ocean floor .and abyssal-dark ,cold and highly pressurized –from 13,000 to 20,000 feet below sea level.

Tidal estuaries represent the border area where bodies of salt water and fresh water meet- a mixing zone that supports a variety of aquatic plants and animals, from algae and seaweeds to fish , oysters, crabs , and numerous species of migratory waterfowl.

Coral reefs are distinctive habitats anchored by colonies of coral ,marine invertebrate species that number in the thousands.

Freshwater habitats are found worldwide –small ponds, large glacial lakes, streams and rivers fed by snowmelt and rain-and support plants and animals adapted to low salt content.
