Marine biomes are divided into ecologically distinct zones depending on

Options:

A) their depth and distance from the shore.

B) their temperature and distance from the shore.

C) the type of plant life present.

D) the type of fish present.

A) their depth and distance from the shore.

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.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
