Who is at the bottom of the food chain in Antarctica?

They are usually single celled and use photosynthesis to make energy. 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. Phytoplankton can be thought of as the base of a food chain or web.

Why is the Antarctic food chain in danger?

Penguins, whales and seals in the Antarctic Southern Ocean could go hungry because of global warming, say scientists, who warn that the population of krill, at the heart of the food chain, has fallen about 80% since the 1970s.

Is the killer whale at the top of the food chain?

Killer whales (also called orcas) are apex predators, meaning they are at the top of their food chain. They feed on fish and squid like other odontocetes (toothed whales) do, but will also target seals, sea birds and even whale species far bigger than themselves.

What is the food web in the Arctic?

In the Arctic, there are several food chains that criss-cross to make a food web, starting with the sun, then producers like phytoplankton in the sea and grasses and lichens on land. Some of the consumers in the food webs are krill, fish, birds, reindeer, and seals.

What eats a shark in a food chain?

Yes! The great white shark has been thought of as the untouchable predator of the ocean, but in fact killer whales (or orcas) are actually quite skilled in attacking a great white. Orca’s hunt in packs, similar to wolves and have been known to work together in tactical ways to capture and attack their prey.

Among the predators of the jellyfish, the following have been identified: ocean sunfish, grey triggerfish, turtles (especially the leatherback sea turtle), some seabirds (such as the fulmars), the whale shark, some crabs (such as the arrow and hermit crabs), some whales (such as the humpbacks).

Can a penguin freeze to death?

If they become waterlogged, they can easily freeze to death in conditions below zero. This sad outcome is something that scientists and guides working in Antarctica are noticing more and more as the continent warms up. ‘I’ve seen it start to rain, and all the poor chicks get completely wet,’ Rudolf said.

What eats Antarctic krill?

Blue whales and other large whales, leopard seals and other seals, several species of penguins, albatrosses and other seabirds, several fish species, and squids and other invertebrates all eat huge numbers of Antarctic krill. Without this species, Southern Ocean food webs would completely collapse.

What are the food chains in Antarctica?

What are the food chains in Antarctica? An Antarctic food chain can begin in the ocean with phytoplankton, microorganisms that release large amounts of oxygen into the air as a byproduct of photosynthesis. These tiny plants are food for the shrimp-like krill. Squid eat krill, emperor penguins feed on squid, and killer whales consume the penguins.

What is a major predator in the Antarctic food chain?

The top of the food chain belongs almost exclusively to the killer whale – the most common predator on the large krill eaters (the penguins, seals and baleen whales) but the leopard seal is a main carnivore on penguins and thus may also be a major top predator as well.

What animal in Antarctica is top of the food chain?

sea ice algae – which live on the underside of the sea ice but may fall to the sea floor

  • phytoplankton – which may be carried under the sea ice by currents from open water regions
  • macroalgae – leafy seaweeds and algae that are attached to rocks and corals on the sea floor
  • microalgae – microscopic algae that lives on the surface of sea floor sediments.
  • What is the food chain of Antarctica?

    In the Antarctic food chain krill are primary consumers and baleen whales, penguins, seals and many kinds of fish and other birds are secondary consumers when feeding on krill. Many animals are a mixture of primary, secondary, tertiary (3rd) and quaternary (4th) consumers as they eat a variety of prey.
