The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F). They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day (that is, about 20 inches a day), ultimately reaching 30 to 80 metres (100 to 260 ft).

Ocean water presents many vastly different habitats based on temperature and nutrient availability, resulting in phytogeographic zones, regions, and provinces. [ 84 ] To some degree, the distribution of algae is subject to floristic discontinuities caused by geographical features, such as Antarctica , long distances of ocean or general land masses.
Aquatic species in the Northern Gold of Mexico are currently migrating there due to climate and finding food source, that many native animals are being out competed for their own food. Thus manatee grasses are being over grazed and resulting in lower nursery areas for native species that rely on the meadows.
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Marine biology is the scientific study of the biology of marine life, organisms that inhabit the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
What you own and consume every day amounts to astonishing numbers over your lifetime. You might not think twice about your daily habits, but putting it into perspective over a lifetime might shock ...
In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish, and baleen whales. Marine plankton include bacteria, archaea, algae, protozoa, microscopic fungi, [4] and drifting or floating animals that inhabit the saltwater of oceans and the brackish waters of estuaries.
