There are many things critical for all of the oceanic ecosystems to survive. First thing, every sea creature relies on all plankton. Plankton are the most targeted prey of the sea; they are fed upon by many creatures such as whale sharks, krill, squid, and small fish like mackerel.

Sea plants and coral are also critical for all reef fish to survive. Coral makes shelter and protection for many fish and many fish like various clown fish and goby fish eat the minerals off of coral.

The most important thing for any part of the ocean is constant temperature throughout each season. Most fish are not capable of adapting to different temperatures and if waters get too hot or too cold, the community will die. Every sea creature survives in a certain temperature and it must be regulated. This is why global warming is a big threat to all of the world, not just the Arctic and Antarctic. So the most important things for oceanic ecosystems are plankton, sea plants, and temperature.
