What are the main producers in Antarctic waters?

Producers in the Antarctic Ocean ecosystem are:

• 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.

What plants grow in the Antarctic?

There are no trees or shrubs, and only two species of flowering plants are found: Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis). These occur on the South Orkney Islands, the South Shetland Islands and along the western Antarctic Peninsula.

What are the 2 plants in Antarctica?

Only two species of vascular plants are found on the entire continent: Antarctic hair grass and Antarctic pearlwort. What sets these apart from other plants, like mosses, lichens, and fungi, is their ability to photosynthesize through their vascular system.

What are some producers in the Arctic?

The producers in the Arctic tundra are scrubby bushes, grasses, mosses, and lichens. Sometimes, there are tertiary consumers that eat secondary consumers. The two organisms are fungi and algae. Many lichens can be covered with ice for up to three years and still remain alive.

Are there resources in Antarctica?

None approach a grade or size warranting economic interest. Also noneconomic are the very large deposits of coal and sedimentary iron.

What are 5 producers in the Arctic?

What are some decomposers in Antarctica?

Decomposers in an Arctic biome may contain, bacteria, the prime decomposers throughout the world. Mosses, lichen, and fungi are also active decomposers but things take a long time to decompose in the tundra because there is only a short window of temperatures warm enough to allow activity.

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.

What is the Antarctic food chain?

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.
