Climate change could cause decline in Antarctic krill habitat
Climate change could cause major decline in Antarctic krill habitat by 2100. 16 August 2016. WASHINGTON, DC — Antarctic krill, small crustaceans key to the Antarctic marine food web, could lose most of their current habitat by the year 2100, according to a new study. Researchers combined climate simulations with a krill growth …
Biogeography of Antarctica
A starting point for understanding Antarctica's biogeography is to consider the factors that affect plant productivity and how these factors vary across the continent. Of course, plants grow by making their own food through the process of photosynthesis (they are autotrophs ), and therefore the key factors affecting plant productivity are the ...

Animals of the Ice: Antarctic Krill | Ocean Today
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.
What is the top of the food chain in Antarctica?
Krill and Its Place in the Antarctica Food Chain Does any food grow in Antarctica? A year-round greenhouse could grow food in polar stations and in space. Antarctica's nonstop winters make it impossible to grow food outdoors. Fruits and vegetables are instead shipped long distances from overseas, just a few times per year. …
