food chains and food webs are necessary as they maintain the ecological balance
Ecosystems in the ocean are called marine ecosystems. Plankton is important to the marine ecosystem because they are food for many animals.
If there was a oil spill the entire ocean ecosystem would be at risk.
The only ecosystem -- food chain, in 'Antarctica' is in the Southern Ocean. The land is too cold to support any kind of ecosystem. The food chain in the Southern Ocean is short -- only seven layers. The deep, cold polar ocean is the most protein-productive salt water on earth. Because the carnivores feed on each other, there seems to be food enough for all.

The squid is very important to the ocean ecosystem, serving as both predator and prey. As predators, they help keep the population of their prey in check. As prey, they serve as important food sources for sperm whales and some other predators.
On what other parts of the ecosystem do snakes depend for food?
The opean ocean is the area beyond the neretic zone. It makes up most of the ocean. It is filled with many different species. It consists of the surface zone, transition zone, and the deep zone. When you go to the deep zone, it is very cold and dark. For more information, look on Wikipedia.

It forms almost every ecosystem because they are the producers and pastures of them. Small organisms eat and big follow.
