A description of the marine biome
The marine biome consists of an aquatic, saltwater environment. It includes all of the oceans and seas and covers nearly 75% of the earth's surface. This means that is the largest classified biome to exist. It is home to the birthplace of all life on planet earth, all life once started in a marine biome to evolve into all of the other biomes on our planet.
It contributes its fair share to the rest of the ecosystem. Algae play a large role in the balance of the global environment, for it provides much of the world's oxygen supply, and is a large consumer of atmospheric carbon dioxide. Also, few people know that a lot of the rainwater we receive here in California is thanks to the evaporation of sea and ocean water.
It is known most well known for its oceans. Oceans are large bodies of water that cover most of the Earth's surface. Oceans can be classified into four zones: intertidal, pelagic, abyssal, and benthic. Each zone contains a great diversity of species, more diversity than land-dwellers, despite the fact that fewer species exist.
If you would like to learn more about these different zones, feel free to browse to the biodiversity page, which goes into detail about each zone and its inhabitants.
