An omnivore is an animal whose species normally derives its energy and nutrients from a diet consisting of a variety of food sources that may include plants, animals, algae, fungi and bacteria. The term means 'all-eater' (Latin, ''omnes'', ''omnia'', meaning "all" or "everything" and ''vorare'' meaning "to devour"), Omnivores are often opportunistic, general feeders that lack carnivore or herbivore specializations for acquiring or processing food, but which nevertheless consume both animals and plants. ==Etymology== The word "omnivore" is a term of convenience, and its significance varies according to the context of the type and degree of omnivory.. ''Omnivore'' is derived from the Latin ''omnis'' (all),() and ''vora'', from vorare, (to eat or devour). Traditionally the definition for omnivory relies on a species "including both animal and vegetable tissue in the diet". The taxonomic utility of this definition is limited, since the diet, behavior, and phylogeny of one omnivorous species might be very different from that of another: for instance, an omnivorous pig digging for roots and scavenging for fruit and carrion is taxonomically and ecologically quite distinct from an omnivorous chameleon that eats leaves and insects. The term "omnivory" is also not comprehensive because it does not deal with mineral foods such as salt licks. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Omnivore」の詳細全文を読む スポンサード リンク
