2. Marine Ecosystem o Oceans major ecosystem is marine ecosystem. o Marine Ecosystem is one of the largest aquatic ecosystem. o It includes oceans, salt marshes, estuaries,and more. o The oceans biome is aquatic. o An aquatic ecosystem is made of a body of water.

3. Producers Only two types of living things in the ocean make food using sunlight. These are called producers. One type is phytoplankton. Huge numbers of phytoplankton, most of them only visible under a microscope, drift with the currents and are food for the zooplankton such as copepods and young urchins!! *The second type are the seaweeds, which are large algae. The largest seaweeds grow low in the intertidal zone and extend out into the s- ubtidal zone. These are the kelps, large brown seaweeds that are glued to the rocks with their holdfast. Their long blades float at or near the surface of the water where they get sunlight to make food, which allows them to grow very fast. Their holdfast glue is very strong, and it can keep the huge kelp in one place even when strong currents and waves occur during storms!!!

8. Primary Consumers!! Primary consumers Primary consumer are basically the herbivores of the ocean. In places like the ocean, the primary consumers are lobster, mussules, and shrimp. Shrimp are still considered primary consumers even though they eat phytoplankton, which are a producer rather than a plant. This is because phytoplankton gets energy from the sun, not plants. You can read more in producers but this is primary consumers. There are many more primary consumers in the ocean but that's what I can think of. You can learn more on other pages.

9. Secondary Consumers!! Harp Seals Bottlenose Dolphins Octopus and Squid Green Sea Turtles Baleen Whale Blue Whale Small Fish Car-beater Seal

10. Decomposers A few decomposers of the ocean are: bacteria, fungus, marine worms, sea slugs, sea worms, brittle stars, etc. There's also Nassarius snails and Sand sifting Starfish. They eat Defrius out of the sand.
