Herbivores which consume land plants may eat any or all of the fruit, leaves, sap, nectar, pollen, flowers, bark, cambium, underground storage organs like roots, tubers, and rhizomes, nuts, seeds, shoots, and other parts of plants; they frequently specialize in one or a few of these parts, though many herbivores also have quite diverse diets. [1]
Eating a second prey type helps herbivores' populations stabilize. [63] Alternating between two or more plant types provides population stability for the herbivore, while the populations of the plants oscillate. [62] This plays an important role for generalist herbivores that eat a variety of plants.

Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers. Heterotrophs can be classified by what they usually eat as herbivores, carnivores, omnivores, or decomposers. [1] On the other hand, autotrophs are organisms that use energy directly from the sun or from chemical bonds.
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.
An herbivorous diet includes subtypes such as granivory (seed eating), folivory (leaf eating), frugivory (fruit eating), nectarivory (nectar eating), gummivory (gum eating) and mycophagy (fungus eating). The digestive tract of an herbivore is host to bacteria that ferment these complex substances, and make them available for digestion, which ...
[11] [13] Changes in plant communities in response to herbivory reflect the differential palatability of plants to the overabundant herbivore, as well as the variable ability of plants to tolerate high levels of browsing. [9] The heights of plants preferred by herbivores can give indications of the local and regional herbivore density. [14]
A Bornean orangutan (Pongo pygmaeus) eating a fruit. A frugivore (/ f r uː dʒ ɪ v ɔːr /) is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. [1]
