Oceans have been one of the first things that have been formed on the planet Earth. What are the things that need to keep it “running”?
In the Pacific Ocean, biotic factors include fish, whales, sharks, dolphins, jellyfish, and a lot more. These are all biotic factors because they are living or once were living. On the other hand, things that are not living and never were living are called abiotic factors. Things like sunlight, water currents, temperature, and many more fall into this category.
In the Pacific Ocean, many organisms coexist with each other and they eat each other. The base of the food web consists of photoautotrophs. Photoautotrophs are organisms that make their own energy via the sun. These are organisms such as phytoplankton,

One is the producer-consumer relationship. One example of a producer-consumer relationship is a jellyfish and phytoplankton. The phytoplankton is a photoautotroph (also called a consumer) and gets its energy from the sun. The jellyfish is classified as the next level above, the herbivores. So, the jellyfish eat the phytoplankton making the relationship a producer-consumer one. The second type of relationship is the predator-prey relationship. This is the relationship where the predator eats the prey. A good example of this is a shark and a fish. The shark is classified as a top predator and the fish a smaller carnivore. Since the smaller carnivore is the main source of nourishment for sharks, the sharks eat the fish. This makes the relationship a predator-prey relationship. The last three relationships are different examples of symbiosis, which is the interaction between two living organisms. The first type of symbiosis is a form called mutualism. Mutualism is where both organisms gain something good from their interaction (+,+). An example of mutualism is a clownfish and a sea anemone. This is because the sea anemone is a shelter for the clownfish who are covered in a special mucus allowing them not to be stung. The clownfish is also provided with food while being housed in the anemone. The anemone is also getting positive things. The clownfish cleans away fish and algae leftovers from the anemone and is also …show more content…
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years. Also, the usage of explosives are harmful because they all kill off things such as coral, and the damaging of coral reefs can take decades before it reverts back to its normal state. To reduce or totally eliminate the way these local practices are impacting the environment, we can place restrictions on what can be used in fishing, and how much you can catch. For example, we can limit fishers to only 10 fish a day. This would give the fish plenty of time to reproduce and would keep the population of the fish steady. Also, we can ban the usage of poisons and explosives. This would stop destroying and polluting the ocean. Instead, we would allow fishers to do other things that would catch fish without such a huge impact on the
