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.
These types of eco-evolutionary feedbacks between plants and herbivores are likely the main driving force behind plant and herbivore diversity. [39] [43] Abiotic factors such as climate and biogeographical features also impact plant-herbivore communities and interactions. For example, in temperate freshwater wetlands herbivorous waterfowl ...
This is one example of how overbrowsing can lead to the loss of reproductive individuals in a population, and a lack of recruitment of young plants. Plants also differ in their palatability to herbivores. At high densities of herbivores, plants that are highly selected as browse may be missing small and large individuals from the population. [18]
An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.
These ancient herbivorous animals clearly demonstrate that the ability to consume plant material evolved very early in the history of lepidosaurs. The evolution of herbivory in squamates (the group that includes lizards and snakes) is less well known, though herbivorous species are found in the fossil record.
A graminivore is a herbivorous animal that feeds primarily on grass, [1] specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing . These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose , which is abundant in fibrous plant matter and ...

Elephants are an example of a mammalian folivore. In zoology, a folivore is a herbivore that specializes in eating leaves. Mature leaves contain a high proportion of hard-to-digest cellulose, less energy than other types of foods, and often toxic compounds. [1] For this reason, folivorous animals tend to have long digestive tracts and slow ...
