**Producers**
The following organisms are some of the producers of the Tundra. All of these are plants because a producer is defined as an organism that can perform photosynthesis and can therefore make its own food. It can also produce its own energy, which they mostly store for themselves, but some is lost as heat. Ten percent of their energy is transfered to higher level consumers. Only plants have this ability. →Arctic Willow = =

→Pasque Flower = =

**Primary Consumers (Herbivores)** These organisms are called primary consumers because they only eat producers. Therefore, they are the first consumers. →Reindeer

→Hare →Lemming

The next highest level of consumption after primary consumers are secondary consumers. These organisms can eat only meat, or they can eat both other animals and producers. However, this consumer cannot be a herbivore because they eat only plants. A secondary consumer is one who eats a primary consumer, who eats a producer. For example: if an ermine eats a hare who eats grass, that ermine is considered a secondary consumer. Here are some examples: → Ermine →Quoll

→Arctic Fox

Tertiary consumers are organisms who eat secondary consumers. Like secondary consumers, they have the ability to be either a strict meat eater or an omnivore, who eats plants and animals. However, in order to be classified as a tertiary consumer, it must eat an animal, who eats an animal, who eats a plant. →Polar Bear →Arctic Wolf
