Herbivores only eat plants in the tundra. hope this answers your question... :)
The primary consumers in the tundra are the herbivores.
There are really no herbivores in the tundra because in the tundra, (Antartica...etc), there is not much plant life. If there even is a single plant in the tundra it would most likely be froze and no animal could eat it.

Many types of herbivores live in wetlands. Some of these are beavers, certain turtles, and deer. Rabbits and mice are often found in wetlands as well.
Some examples of herbivores in Taigas are American Elks, Yellow Bellied Sapsuckers (a bird), and American Dippers (another bird)
