Explanation:
Marine life, or sea life or ocean life, is theplants, animals and other organisms that live in the salt water of the sea or ocean, or thebrackish water of coastal estuaries. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms produce much of the oxygen we breathe. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land.
Most life forms evolved initially in marine habitats. Oceans provide about 99 percent of the living space on the planet.The earliestvertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians which spend portions of their lives in water and portions on land. Other fish evolved into land mammals and subsequently returned to the ocean asseals, dolphins or whales. Plant forms such as kelp and algae grow in the water and are the basis for some underwater ecosystems.Plankton, and particularly phytoplankton, are key primary producers forming the general foundation of the ocean food chain.
