What is the Importance of krill to the Antarctic ecosystem?

Question

It feeds a lot of animals right?

Answer 1

The Southern Ocean food web is relatively simple, with a single species, krill, being the major item in the diet of many of the predators; fish, squid, penguins, seals and whales. The developing fishery for krill raised an important conservation issue that is being addressed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Answer 2
