Usually in the tundra organisms dont have to worry about competition; the tundra is too big and not many animals can survive against the harsh climate. However, an example of competition could be between a musk ox and a caribou. A musk ox's diet consists of plants such as sedges and grasses, while a caribou's is made of berries, grass and sedge. When food is hard to find musk ox and caribou might have some competition trying to get something to eat. Might be hard to find a musk ox fighting for a sedge with a caribou, though.
The tundra is an example out of many biomes

one example of competition in the artic is between polar bears and the artic wolf. both compete against each other for same source of food, which tend to be other animals you could also mention intraspecific competition between producers, for example in winter months when sunlight is scarce grass will compete for sunlight
Density dependent limiting factors are weather, predators, and competition between spices. e.g if there are too many rabbits in a an ecosystem rabbits will have other rabbits as competition because of the too little food.

Footraces between humans are an excellent example of competition.
The question, as stated, is incomplete. Did you mean to ask what is an example of a preditor/prey relationship? pair? I'll assume you meant preditor prey species pair. Here are a few: Wolf-deer Hyena-wildebeest Coyote-rabbit Owl-pigeon Human-just about anything
Both Fireweed and Horsetail are wildflowers of the tundra as well as Silverweed and Lupine.
