Explanation:

    The marine environment occupies about 71% of the land surface, its deepest parts reach almost 11,000 meters. In this environment two domains are distinguished: the benthic, which corresponds to the seabed, where benthic organisms are fixed or moving on the substrate, and the pelagic, which comprises the body of water, where organisms that swim actively predominate.

    As for light penetration, the marine environment has three distinct regions: euphotic zone - the most superficial region that receives the most sunlight; dysphotic zone - dimly lit region; aphotic zone - totally absent lighting.

There are three categories of marine communities:

In the Coastal Marine biome are important ecosystems such as mangrove swamps, coral reefs and estuaries.
