Within the marine fauna, the following groups stand out due to their number, abundance and size: Fish, Mollusks, Arthropods (different types of crabs, lobsters, shrimp, etc.) and Cnidarians (living waters, corals, anemones) .

fauna (p)

Most ocean flora consists of microscopic algae called phytoplankton that float on the surface and through photosynthesis produce about half of the oxygen that humans and other land creatures breathe.

Human Activities and Consequences (a)

The marine ecosystem (a unit of unique biological communities consisting of a variety of coexistent flora and fauna species) plays a major role in regulating atmospheric oxygen, carbon dioxide, and filtering the pollutants in the water.

ocean ecosystem

Thank you!

The Atlantic Ocean is the ocean that separates America, to the west, from Europe and Africa, to the east and extends from the Arctic Ocean, in the north, to the Antarctic, in the south , forming the second largest ocean on the planet after the Peaceful.

attarctic ocean (b)

Oceans cover more than 70 percent of the Earth's surface, and half of those waters are at least 1.86 miles (3 km) deep. 2. As far as we know, the ocean is 36,200 feet (11,000 m or almost 7 miles) deep at its deepest point. On average, the ocean is about 12,100 feet (3,688 m) deep.

Open sea
Rocky shores

A rocky shore consists of rocky ledges with pools of salty water, boulders and pebbles. Living in this habitat is a community of hardy plants and animals and each species is specially adapted for coping with the harsh environment around it.

Sandyt Beach

The sand that makes up beaches is eroded from inland rocks, flows down creeks and rivers, and then is deposited at the mouth, forming sandy beaches. Longshore currents generated by waves pick up sand grains from these larger deposits and move them along the coast to form more beaches.

The most striking feature of the Atlantic seabed is a large underwater mountain range that crosses it from north to south, called the Mid-Atlantic Ridge , which is formed at the boundary of four tectonic plates: Eurasian, North American, South American and African.

The Arctic Ocean is the smallest of the planet's oceans. It surrounds the North Pole and extends to northern Europe, Asia and America . It occupies an area of ​​about 14,100,000 km² and one hundred m on the continental shelf; its average being about 1205 m.

Arctic Ocean (r)

The Indian Ocean is the third largest volume of water in the world, covering approximately 20% of the Earth's surface . It is limited to the north by southern Asia; to the west by the Arabian Peninsula and Africa; to the east by the Malay Peninsula, the Sunda Islands, and Australia; and to the south by Antarctica.

i indian ocean (a)

The Pacific Ocean is the largest and deepest on Earth . It covers more than 155 million square kilometers from the west coast of America to the east coast of Asia, and has an average depth of more than 4,000 meters, exceeding 10,000 meters in the Mariana Trench (the deepest point on the planet )
