the producer might be reindeer moss,
the herbivore could be an acrtic moose, if those exist, or an animal that lives in the arctic tundra that only eats plants,
the carnivore might be an Arctic fox, and the decomposer could be fungi
The food chain is alive and thriving in the Arctic tundra. First, there is bacteria in the water, which small fish eat off of. The lakes are shallow. It is also very cold there, so most of the animals living there have fur coats, thick hide, lots of feathers, etc. Well In the primary producers is grass and other small flower-like plants that survive cold climates. Plants are short because the ground is warm, and they like being warm. Some plants even have hair. Next is the primary consumers. There are musk oxen, insects like mosquitoes, and lemmings. (rat-like creatures) Small predators, like the Snowy Owl and the Arctic Fox feed off of mostly the lemmings. There are much more animals I didn't mention, but I hope this gives you an idea of what its like! :)
Yes, lichens in the arctic tundra food chain are considered primary producers rather than consumers, as they make their own food through photosynthesis using sunlight, water, and nutrients from the soil. They are an important food source for herbivores like caribou and musk oxen in the arctic tundra ecosystem.
Polar Bears Arctic Fox's Coyotes Grizzly bears Killer Whales
They try to eat very warm food, they also hunt for fish and animals in the Arctic tundra.
Yes, polar bears are on the top of the Arctic food chain. Then the seals.
Tundra. The arctic tundra in the summer and then they migrate to the Boreal Forest in the winter.
Arctic Foxes and scavenger birds
If you mean Arctic tundra then yes.
Yes.
there are no decomposers in a tundra
Simplistically, from their food. However, the base of the food chains, the producers of the tundra, are the plants such as arctic mosses, which photosynthesise like plants everywhere.
north siberian plain
It means that only the strongest organisms in the tundra can survive, like the polar bears who are on top of the food chain in the arctic. Also there is low number of different organisms there.
