The largest aquatic ecosystems are oceans, with seas come in second. It is huge and can change quickly.
Water Circulation: Water circulation is affected by serveral factors including the direction of the wind blowing. Another important factor that applies more to the Arctic and Antarctica is water heating and cooling. The water is charged with oxygen that makes it flow.
Supply of oxygen: Oxygen supply can change with the decomposing of dead beings. When the ocean decomposes these dead beings, it requires oxygen, which can lead to oxygen depletion. Most oceans regenerate oxygen quickly, but in some parts of some oceans, the regeneration of oxygen is slower or there are too many dead beings, which leads to oxygen depletion.
Ocean Cycles: In the ocean, many parts are darker and rely on detritus to sustain plant growth. They release nutrients that sustain plant growth, which in turn sustain animals, all the way to the top of the food chain.
Impact of pollution: The ocean receives people's garbage. Some go to animals like small krill that accidentally feed on microplastics. DDT is also a hazard and as microplastics and other garbage go from krill to fish, it would also reach us. When krill and other small creatures accidentally take in microplastic, it can spiral up the food chain. For example, whales feed on krill and while a bit of microplastic is mostly fine, especially for a whale, it can build up as it eats more krill that contains microplastic. It also goes to fish and squid, which humans eat. This can all add up and would pose health hazards not just to the ocean but also to us, the ones who were responsible for the microplastic in the first place. Lead can also be a huge problem as it builds up in oceans and irreversible things can happen. But while the microplastic can build up and lead is very dangerous, a very big problem is oil spills. This can affect everything in the food chain till the point of no return and is something that is very hard to deal with while we still must use gas.
