In the Antarctic ecosystem, different kinds of organisms present that can be understood by the food web available there. The food web is very complex in the Antarctic ecosystem. Phytoplanktons are producers in this food web and krill are primary consumers.
Krills are important animals of this ecosystem as most of the secondary consumers including fishes, baleen whales, penguins, and seals and many birds are feeding on krill. The various species eat fish, penguins, squid, and krill.

Sea level is generally used to refer to mean sea level (MSL), an average level for the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datum – a standardised geodetic reference point – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order tocalibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location.
Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, and sea level risehas been widely quoted as evidence of ongoing global warming.
The term above sea level generally refers to above mean sea level (AMSL).
