Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The snowy owl (Bubo scandiacus), [4] also known as the polar owl, the white owl and the Arctic owl, [5] is a large, white owl of the true owl family. [6] Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. [2]
Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears. These animals have been endangered due to overhunting, an infestation of disease, loss of diet and habitat due to climate change, and human destructive activities, such as searches for natural gas and oil, mining, and road building.

They are prey for animals like coyotes, mountain lions, Arctic foxes, lynx and bears. Injured, sick, weak, old and young reindeer are the most at risk when it comes to predators.
This is a list of large carnivores known to prey on humans. The order Carnivora consists of numerous mammal species specialized in eating flesh. This list does not include animal attacks on humans by domesticated species (dogs), or animals held in zoos, aquaria, circuses, private homes or other non-natural settings.
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic tundra, [ 2 ] alpine tundra , [ 2 ] and Antarctic tundra.
A pika (/ ˈ p aɪ k ə / PY-kə, [3] or / ˈ p iː k ə / PEE-kə) [4] is a small, mountain-dwelling mammal native to Asia and North America. With short limbs, a very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. [5]
Sometimes there is debate whether the muskox or the Arctic hare is the primary prey for the hare-wolf-muskox predator-prey system. Studies provide evidence that the muskoxen are indeed their primary prey because wolf presence and reproduction seems to be higher when muskox is more available than higher hare availability. [ 23 ]
