Transcript of Copy of Antarctic Ocean

Antarctic Ocean: description The Antarctic Ocean is the fourth out of five largest oceans in the world
It's oceans motion moves towards the eastern direction
Meets with many oceans Has the strongest winds than anywhere else in the world Geographic locations on Earth Statistics Succession Pioneer Species & Climax Community Decomposers The average precipitation of rainfall is 10 inches of snow. STATISTICS The average seasonal temperature is 10 Celsius Antarctic Ocean Pineer Species & Organisms Young Icefish eat krill Octopus eats Krill Young Icefishes are in cold waters. They won't freeze in water because their their blood avoids them from getting frozen. This octopus is very common. Feather Star eats Phytoplankton

A Feather Star can move very easily. Sort of like a feather. Comb Jelly eats Zooplankton Many Comb Jellies are at the bottom of the Antarctic ocean floor Krill eats zooplankton Krill is eaten by humans and fish, or used as bait when people go fishing. Decomposers barnacles on a whale. Mutualism, parasitism, & commensalism whale Worms in a fish. Remoras on a shark. Food : Emperor penguins, Weddel seals, Ross seal, large fish, & tooth whales all eat small fish squid. Competition For Resources Water : Space : Scale worms eat little leftovers of a starfish's food. Sandhoppers eats pieces of dead animals at the beach at night. Sandhoppers are found at the beach. Scale worms are found on rocky shores. They live in the water. Also when
humans cause global warming. Icebergs come at random times Succession Huge waves and wild winds Space isn't an issue the animals choose to remain in packs, but if the poputation is very high then there can be some problems. For economic beniefit they almost made some species extinct Human Impact Killing and desturbing other animals. Comaminating oils Washed up waste Food webs Serolid Isopod Crustaceans eat rotten plants and animals. These decomposers look like as if they were squashed. The dead organisms are recycled by the decomposers. They eat the leftovers. An animal kills the organism and then these decomposers eat the rest of it. Recycling Organisms Phytoplankton - It is a limiting factor because its' productivity has been reduced caused by increased solar ultraviolet.
Krill - because phytoplankton is a limiting factor, that results in a decreasement in the krill population.
Climate change - This is another limiting factor that threatens krill populations too. Limiting Factors of the Antarctic Ocean
