Question

What does krill eat in an ecosystem?

Answer 1

The lowly krill averages only about two inches in length, but it represents a giant-sized link in the global food chain. These small, shrimp-like crustaceans are essentially the fuel that runs the engine of the Earth’s marine ecosystems.

Answer 2

This ice loss removes a primary source of food for krill: ice-algae. Krill is a cornerstone of the entire Antarctic food chain. Krill, especially the larvae, are dependent in winter on sea ice. Krill are the main diet for hundreds of different animals, from birds to whales.
