Pacific Ocean Ecosystem
Transcript of Pacific Ocean Ecosystem
Biotic factors are living creatures, here are biotic factors of the pacific ocean.
Biotic Factors: fish, whales, sharks, dolphins, plants, jellyfish, plankton, coral (coral is both biotic and abiotic), sponges, shrimp, starfish, squids.
Abiotic factors are non-living creatures, here are abiotic factors of the pacific ocean.
Abiotic Factors: sand, underwater volcanoes, shells, rocks, coral, salt water, soil, pebbles, trash.
Producers are the living things that get energy from the sun, that's called photosynthesis. Primary consumers eat plants to get there energy.
Some Producers: Seaweed, phytoplankton, diatom, crill, algea, dinoflagellates.
Decomposers are living things that break down bodies and other things so that the ocean is isn't full of what we call left overs. They also clean up all the floating things in the water so fish can see.
Some Decomposers: bacteria, crabs, marine worms, shrimp.
A population is a large group of one species for example the shark all the sharks in the world would be the population of the sharks. One clown would be an individual. Population is kind of another word for group.
A community is a group of different animals working to make a living place. Like the human community different humans do different jobs. Fish in the ocean also have jobs to keep the ocean livable. There are many cleaner fish that clean the water and eat dead fish. There are sharks and whales that if you think about it they help the ocean by making sure the ocean isn't overpopulated. Small fish eat
How Do human's Impact this ecosystem?
Humans impact this ecosystem a lot more then we think. Every year we dump more then 180 million tons of toxic into the ocean, That killing fish then other fish have less food and die and so on until they get changed to eating other fish that they don't know how to hunt/eat. That again kills more fish until top predators are dying then fish start dying. We can stop this from happening by not using plastic and if you do then make sure to recycle your plastics.
A food web is a system of showing which biotic factor consumes the other biotic factor. for example a tuna fish is a top predator that eats shrimp and the shrimp gets the energy from eating the seaweed and the seaweed got its energy from the sun.
Microorganisms are pretty much the same as decomposers except 3-4 billion years ago they were the only living thing them evolved. They also live deep inside rocks within the Earth's crust.
Animals In a Pacific Ocean Community
Since there isn't really one and only community in the pacific ocean I'm going to name some fish in a community.
- Sea Turtles
Producer's need sunlight to do photosynthesis
to get energy for the primary consumer to get there energy. (So it's important for producers to get sunlight to be able to feed the primary consumers) It's important then for the primary consumers to have plants and then its important for the secondary consumers to have the primary consumers eat the plants and it's the same cycle from there.
