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.
Herbivore is the anglicized form of a modern Latin coinage, herbivora, cited in Charles Lyell's 1830 Principles of Geology. [3] Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. [3] Herbivora is derived from Latin herba 'small plant, herb' [4] and vora, from vorare 'to eat, devour'. [5]
[3] Primary consumers are herbivores, feeding on plants or algae. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants). There are certain primary consumers that are called specialists because they only eat one type of producers.
Examples of monogastric omnivores include humans, pigs, hamsters and rats. Furthermore, there are monogastric carnivores such as cats. [1] A monogastric organism is contrasted with ruminant organisms (which have four-chambered complex stomachs), such as cattle, goats, and sheep.

Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
For example, there are roughly 3,300 species of living lizards and approximately 3% of them eat at least some plants. [4] Though the exact definition of herbivory varies significantly between scientists, most define herbivorous lepidosaurs as those that consume plants for approximately 70-90% of its diet.
An example comes from the research of Tim Clutton-Brock, who found that the black-and-white colobus, a folivore generalist, needs a home range of only 15 ha. On the other hand, the more specialized red colobus monkey has a home range of 70 ha, which it requires to find patchy shoots, flowers and fruit.
