Antarctic Krill Food Chain

Antarctic Krill Food Chain In the antarctic food chain krill are primary consumers and baleen whales, penguins, seals and many kinds of fish and other birds are secondary consumers when feeding on krill. many animals are a mixture of primary, secondary, tertiary (3rd) and quaternary (4th) consumers as they eat a variety of prey. In antarctica and the southern ocean, the food web begins with microscopic plants called phytoplankton. these ‘feed’ on the energy of the sun. phytoplankton are food for antarctica’s most important species – antarctic krill. krill look like smaller versions of familiar crustaceans such as prawns or shrimp. they are mostly transparent.

Antarctic Krill Food Chain Antarctic krill is the keystone species of the antarctic ecosystem beyond the coastal shelf, [22] and provides an important food source for whales, seals (such as leopard seals, fur seals, and crabeater seals), squid, icefish, penguins, albatrosses and many other species of birds. crabeater seals have even developed special teeth as an. Krill is a general term used to describe a group of about 86 species of small shrimp like crustaceans found throughout the world's open oceans. while they may be small — generally about the size of your thumb — they play an important role in the food web. for example, euphausia superba, or antarctic krill, is a species only found in the. Krill are a critical food source for many of the larger species at the top of the marine food chain. in one day, a single blue whale can consume 3.6 million krill, a single crabeater seal can consume 11,000 krill and an adélie penguin can consume 1,200 krill. that’s a lot of krill in one day!. Assessing climate induced changes in the antarctic ecosystem requires accurate modeling of antarctic krill, the centerpiece of the food chain. there is little consensus regarding the main factors determining krill abundance, which is perhaps expected given the extreme scales among relevant environmental and climate factors involved.

Rapid transport of carbon to the deep ocean sea floor is also facilitated by the short phytoplankton krill whale food chain, where krill carbon is stored as biomass in baleen whales for decades. Narrator: krill are small crustaceans found throughout the ocean. they play an important role in the aquatic food chain, particularly in the southern ocean. antarctic krill provide a vital food source for whales, seals, ice fish, and penguins. these animals depend on eating large quantities of krill for survival in the harsh climate.
