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.
The intermediate levels are filled with omnivores that feed on more than one trophic level and cause energy to flow through several food pathways starting from a basal species. [14] In the simplest scheme, the first trophic level (level 1) is plants, then herbivores (level 2), and then carnivores (level 3).
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 ...
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.

Generalists such as raccoons can sometimes adapt to urban environments and other areas modified by humans, becoming examples of urban wildlife. Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be
This list of carnivorous plants is a comprehensive listing of all known carnivorous plant species, of which more than 750 are currently recognised.
