Solutions
Marine Ecosystems are the largest of Earth's aquatic ecosystems. They consist of five oceans: Atlantic, Pacific, Indian, Southern, and Artic.

South Pacific Ocean
Food Webs
Food webs/chains in every environment are made up of trophic levels.
The trophic levels contain producers always being on the first level. Then consumers on the next levels, and decomposers on the final levels.
South Atlantic Ocean
An example of a food web in the marine ecosystem would be the following:
Producers
Phytoplankton
Coralline Algae
Filamentous Turf Algae
Soil Profile
Seaweed
Consumers
Primary
Secondary
You may also find other stuff at the ocean´s floor, like volcanoes, reefs, shipwrecks, etc.
Tertiary
Zooplankton
Inverterbrate Larvae
Benthic Grazers
Coral
Sea Urchins
Crabs
Green Sea Turtles
Herbivorous Fish
Coral Feeders
Benthic Feeders
Fish Feeders
Plankton Feeders
Decomposers
Dolphins
Seals
Marine Worm
Quartenary
Great White Shark
Killer Whale
Overfishing
Blast Fishing
Pollution
Nets
Standing on Coral
Coral Mining
Cyanide Fishing
Anchoring Ships

-Volunteering at coral reef cleanups
-Practice safe and responsible diving/snorkeling
-Dispose of your trash properly
-Use ecological or organic fertilizers
-Support reef friendly businesses

The marine biome is composed of different types of soils.
One of them is sand, which is just crushed coral and rocks
Another one are the rocks, depending on what part of the ocean you are, you will have different types of rocks. Corals are also part of the soil profile, and last but not least dirt.
Relationships and Competition
Mutualism: Clownfish and Anemone. The clownfish hides in the anemone and scares off butterfly fish. Also there are the remoras and sharks.
Commensalism: Crustaceans who use sponges as a home,
Parasitism: Toxoplasma gondii is a parasite that has killed several sea otters.
Interspecific Competition: Sponges and coral for space, fishes and shrimp for plankton, and alage for sunlight
Food Web
Temperature is lower because of the Agulhas Current that carries warm water from the Indian Ocean to the Atlantic Ocean. Also this had caused the South Atlantic Ocean to have thermocline waters. This leakage has been increasing in the last decades.
