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.

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.
Herbivores form an important link in the food chain because they consume plants to digest the carbohydrates photosynthetically produced by a plant. Carnivores in turn consume herbivores for the same reason, while omnivores can obtain their nutrients from either plants or animals. Due to a herbivore's ability to survive solely on tough and ...
Herbivores, as primary consumers, eat the plant material directly to digest and absorb the nutrients, while carnivores and other animals on higher trophic levels indirectly acquire the nutrients by eating the herbivores or other animals that have eaten the herbivores.
Humans’ impact on biodiversity—via both habitat loss and the effects of man-made climate change—has caused irreversible damage to wildlife, argues a 2023 paper published in the journal PNAS.
The heights of plants preferred by herbivores can give indications of the local and regional herbivore density. [14] Compositional and structural changes in forest vegetation can have cascading effects on the entire ecosystem , including impacts on soil quality and stability, micro- and macro- invertebrates , small mammals, songbirds, and ...
