Their poo is this distinctive colour because of the food they eat. These forms are extremely widespread and are reported as far as latitude 87 S. In addition, Antarctic seas are highly productive in plankton plant life, particularly in near-shore, nutrient-rich zones of upwelling. At the top of the food chain, there are Orcas, often known as Killer Whales. , which means that they generate so little heat internally they (Photo courtesy of Rebecca Gast, WHOI), Young (juvenile) krill that were collected in a net. Carnivores, organisms that consume animals, and omnivores, organisms that consume both plants and animals, are the third trophic level.

The word petrel appears in the names of several birds within the order Procellariiformes. They have large black eyes. food chain. moraine Herbivores are plant-eating organisms that can range in size from tiny insects to large mammals. Organisms in the food web are grouped into trophic, or nutritional, levels. There are many different types and species of phytoplankton, for example, one type is called the diatoms, of which there are around 100 known species. Diatoms, a type of algae, are especially abundant. (Only one species, the Galpagos penguin, is also found in the Northern Hemisphere).

Antarctic Krill grow to around 6 cm (2.4 in). These blooms are densest at the ice edge, so Antarctic krill are often also densest near that system. little muscle (red-brown) there is.
