Antarctica food web is less complicated than the other food webs of the world. However, the Antarctica food web definitely includes much more numbers of animals as compared to any other ecosystem. This Antarctica food system involves the second largest numbers of mammals in the world namely the crab eating seals. This web includes phytoplankton, krill, herbivorous zooplankton, carnivorous zooplankton, fish, birds, seals, leopard seal, elephant seal, penguin and whales.
Another important aspect of food in Antarctica involves that kind of food, which is eaten by those on the polar expeditions. They are provided with a balanced diet, which is dehydrated so that it provides the highest amount of energy, making the body work smoothly. As the entire continent is covered with deep snow, normal vegetation is impossible at the place. At the research stations, some amount of crops is grown under specially created condition.
In the Antarctica regions, there is always a shortage of fresh vegetables and these are mostly grown on hydroponic system equipped stations. It is illegal to import soil or other similar materials to the lands of Antarctica since it threatens an outbreak of non-native insects, bacteria or fungi resulting in incurable diseases. This might poorly affect the hydroponic system of Antarctica and result in a closure of the same.
