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 Alaskan hare (Lepus othus), also known as the tundra hare, is a species of mammal in the family Leporidae. [2] They do not dig burrows and are found in the open tundra of western Alaska and the Alaska Peninsula in the United States. They are solitary for most of the year except during mating season, when they produce a single litter of up ...
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
It is an introduced animal on many of the state's islands due to turn of the 20th century fox farming. Red foxes, which are most common south of the Arctic tundra, prefer low marshes, hilly areas, and broken country. Where the red fox's range overlaps with that of the Arctic fox, the red fox dominates.
In the north, only the hardiest cold-tolerant vascular plants can survive, such as sedge and cotton grass . In a few low-lying, protected areas there can be small stands of Arctic willow (Salix arctica), Dryas species, and low-growing purple saxifrage (Saxifraga oppositifolia), Kobresia species and arctic poppy (Papaver radicatum).
