There is no food chain on the continent.
In the Southern Ocean, however, you can find the shortest food chain on earth. The base of this food chain is Antarctic Krill, properly Euphausia superba.
The Antarctic food chain exists in the Southern Ocean which surrounds the continent. There is no food chain on land.
The Southern Ocean food chain operates like every other ocean sea chain -- except that this one is the shortest food chain.

The food chain is almost entirely based a small shrimp-like animal called krill. This animal is then eaten by the humpback whales, crab-eating seals, squid/other fish, snow petrels and Adelie penguins.
These crab-eating seals, squid/other fish and Adelie penguins are then eaten by Leopard Seals. Squids/other fish are also eaten by Emperor penguins and Sperm whales. Sperm whales, Leopard seals and Emperor penguins are all eaten by Killer whales which eat almost everything, and are known as "apex predators".
There is no food chain for land animals on Antarctica, because there are no land animals that live there.
the food chain in Antarctica is a picture showing what animal eats what for example the killer whale eats krill.
There are no spiders on Antarctica: there's no food chain for them there.
