The dominant herbivors in the Antarctic food web is indeed krill.
which organism is the carnivore in this food web ? a. Krill, B. marine Phytoplankton, c. adelie penguin , d. zooplankton?
The food web around the Antarctic continent -- no food grows on the continent: it's too cold -- exists in the Southern Ocean. This is a short food chain based in krill.
no they dont. Whales typically eat krill, tons and tons of krill! Unless its an orca or the like in which case they eat seals n such :)
Answer is primary consumer. (depending on the type of web you are constructing) krill is a primary consumer or secondary because the primarys include phytoplanktons, zooplankton algae etc and since kill eat phyto and zoo plankton it would be a primary consumer or in a food web it would be in the second bottom row making it secondary in the food piramid or web. eg. bottom row: phytoplankton and zooplankton second bottom row: krill, prawns, and fish then the next up are the tertiary and quaternary row, which are the higher levels in the food web.

the krill is the base because many sea animals eat it.
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.
New energy enters the food web, and matter is created as it moves through the web
That ultimately depends on how big the food web is (how many chains were linked together to create the web). There must always be more than one, though, to keep a food web (and the ecosystem(s) it describes) alive.
