Marine Ecosystem Flashcards
It is a type of ecosystem that is composed of salty water that covers most of the earth’s surface. That type of water is also called as ocean or marine water.
It is among the largest of earth’s systems.
It is the most prevalent type of system that possess high amount of salt content.
Marine Ecosystem
It is a large body of salt water that covers approximately almost 71% or earth’s water.

Intertidal zone organisms
Sea stars, Mussels, Crabs, Clams, Krill, Snails, Seaweeds, Algae, and etc.
Neritic zone organisms
Sea anemones, Shrimp, Lobster, Jellyfish, Oysters, Sponges, Zooplankton, Crabs, Kelp forest, Plankton, Coral reef plants, Algae, and etc.
Oceanic zone organisms
Fish, Whales, Sharks, Dolphins, Jellyfish, Tunas, Corals, Seaweeds, Algae, Phytoplankton, and etc.
Photic zone organisms
Fishes, Marine mammals, Worms, Sea stars, Reptiles, Whale, Phytoplankton, Zooplankton, Dinoflagellates, Diatoms, Cyanobacteria, Coccolithophorids, Cryptomonads, and etc.
Aphotic zone organisms
Giant squid, Jellyfishes, Eel, Algae, Anemones, Anglerfish, Copepods, Mussels, Lantern fish, Crustaceans, Ctenophores, Dinoflagellates, Fangtooth, segmented worms, and etc.
Benthic zone organisms
Green algae, Brown algae, Red algae, Crabs, Sea stars, Worms, Corals, Snails, Demersal fish, Pelagic fish, Epifauna, Bivalves, and etc.
often deposit feeders, obtaining nutrition from ingesting biota, organic and inorganic particles from the sediment surface or within the sediments.
( Bottom part of the ocean – crawling, burrowing, or sessile. )
Benthic
a plant or animal that inhabits the open sea and the surface of a lake, sea, or ocean.
( Living in the water – swimming or drifting )
Pelagic
– cannot swim against ocean currents.
Plankton
– can swim against ocean current.
Nekton
Organism cannot swim against ocean current; therefore, ocean carries them. They float in the water.
Plankton
that uses sunlight for photosynthesis tin order to make planktonic foods.
Phytoplankton or also known as microalgae ( plant-like )
are the small aquatic animals who are weak swimmer.
Zooplankton or also known as microplankton ( animal-like )
Photosynthetic
Creates most of the earth’s oxygen and they are one of the organisms who remove carbon dioxide from the air.
Must stay on photic zone to survive because planktons are sinking, phobic zone is great place to access sunlight.
Common name: Algae
Phytoplankton
Several types of phytoplankton
Diatoms
Dinoflagellates
Cyanobacteria
Single-celled algae
Have intricate glass shells
Form chains to increase surface area
are responsible for 20% of global carbon fixation and 40% of marine primary productivity.
Only organism that has transparent cell wall.
Diatoms
Have 2 flagella or the organelle that are responsible for motility of cell or bacteria.
The 2 flagella are: one wraps around the middle , and other is at the tip.
Cause red tide because of the over population of their species, and they release red plastids.
Dinoflagellates
Also called blue-green algae.
Stromatolites ( clumps of cyanobacteria )
Some are several million years old.
Can be found in all types of water, therefore, it can be found all over the world.
They are responsible for the oxygenation of the atmosphere and oceans.
