What effect would a drop in the size of the of the krill population have on the Antarctic food web and why?
Euphasia superba, Antarctic krill, are the base of the food chain in the Southern Ocean that surrounds Antarctica.
Any decline in their population would mean that the remainder of the food chain would be forced into warmer water to find food.

What does the antarctic ice fish eat?
Antarctic ice fish primarily feed on krill, small fish, and amphipods. They have evolved unique adaptations to survive in the cold waters of Antarctica, such as specialized digestive enzymes to help them digest the high-fat content of their prey.
What is the most abundant animal by weight?
The Antarctic krill, Euphausia superba, is considered one of the most abundant animal species by weight on Earth. They play a key role in the food chain in the Southern Ocean and are a vital food source for marine animals like whales, seals, and penguins.
If all frogs died would the raccoon population decrease?
It is unlikely that all frogs dying would have a significant impact on the raccoon population. Raccoons have a varied diet and can adapt to changes in their environment by consuming other prey items. While frogs may be a part of a raccoon's diet, their absence is unlikely to cause a substantial decrease in the raccoon population.
How does the whale fit into the web of life?
Large whales such as the baleen whales, (Humpback, Blue Whales, etc.) feed on krill, which in turn feed on algae. Say these whales were to become extinct, then there would be a large population of krill. All the krill would eat the algae, and may cause starvation for other animals. Also, algae in the ocean provides most of our oxygen, so this in turn can cause problems for humanity.
How would the population of animals in a prairie community be affected if one is a overhunter?
The population of animals in a prairie community would be negatively affected if one is over hunted because it would change the populations of the other species. This makes the ecosystem unbalanced.
What does antarctic krill do for the natural environment?

What would happen if Krill disappeared in Antarctic?
Then alot of animals would be hungryAnother AnswerAntarctic Krill form the base of the food chain in the Southern Ocean. Without them, the animals in that food chain would be forced into warmer water for food, where they may not survive, based on their invasion of a different food chain.
What continent has the lowest birthrate?
I would assume the Antarctic because it has no births and a small population.
What is the role of krill in the Antarctic food web?
Krill are very small crustaceans of the sea that eat even smaller creatures, called phytoplankton. Krill are called a keystone species because they provide food for a large number of larger animals. If the krill were to disappear, so would all the creatures that eat them. The animals that eat krill are baleen whales, manta rays, whale sharks, many species of seals, fish, and seabirds.
