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.
Energy pyramid
Consumers are heterotrophs and do not get their energy directly, but by eating organisms that do, or by eating other consumers. Herbivores are primary consumers, predators are secondary or higher. Detrivores consume the dead matter left by either producers, or consumers, or both.
scorpions are consumers because they eat other animals to obtain energy.
Consumers use in the ecosystem the energy resource at their level of energy as food.The consumers in the plant kingdom at the trophic level are autotrophs and use solar energy while at the next level the consumers are herbivores and the next level the omnivores and finally the decomposers who feed on decayed organism in the ecosystem.
90% of the energy is lost every time something is consumed.
The primary consumers in the tundra are the herbivores.
whales consume seals
The polar bear and arctic fox.
arctic foxes, falcons
Secondary, tertiary and fifth level consumers, or Apex consumers are the primary residents in the Tundra biome. This includes Arctic foxes, polar bears, caribou, and the snowy owl.
your mom lol :D
tertiary consumer in the prairie is Coyote
Consumers such as Caribou, Musk Oxen, Arctic Hare, and Arctic Ground Squirrels.

Consumers Energy was created in 1886.
A first level consumer is one that consumes producers (plants) directly. First level consumers in the tundra biome would include small herbivores such as lemmings and rabbits, and large grazers such as elk.
They are consumers.
