Lions are obligate carnivores consuming only animal flesh for their nutritional requirements.. A carnivore / ˈ k ɑːr n ɪ v ɔːr /, or meat-eater (Latin, caro, genitive carnis, meaning meat or "flesh" and vorare meaning "to devour"), is an animal or plant whose nutrition and energy requirements are met by consumption of animal tissues (mainly muscle, fat and other soft tissues) as food ...
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 liger is the offspring of a female tiger and a male lion and the tigon the offspring of a male tiger and a female lion. [45] The lion sire passes on a growth-promoting gene, but the corresponding growth-inhibiting gene from the female tiger is absent, so that ligers grow far larger than either parent species.
The largest living land animal, the African bush elephant, is a herbivore. This is a list of herbivorous animals, organized in a roughly taxonomic manner. In general, entries consist of animal species known with good certainty to be overwhelmingly herbivorous, as well as genera and families which contain a preponderance of such species.
Oligophagy is a term for intermediate degrees of selectivity, referring to animals that eat a relatively small range of foods, either because of preference or necessity. [2] Another classification refers to the specific food animals specialize in eating, such as: Carnivore: the eating of animals Araneophagy: eating spiders; Avivore: eating birds
The efficiency with which energy or biomass is transferred from one trophic level to the next is called the ecological efficiency. Consumers at each level convert on average only about 10% of the chemical energy in their food to their own organic tissue (the ten-per cent law). For this reason, food chains rarely extend for more than 5 or 6 levels.
An omnivore (/ ˈ ɒ m n ɪ v ɔːr /) is an animal that regularly consumes significant quantities of both plant and animal matter. [3] [4] Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. [5]
In zoos, lions have been bred with tigers to create hybrids for the curiosity of visitors or for scientific purpose. [39] [40] The liger is bigger than a lion and a tiger, whereas most tigons are relatively small compared to their parents because of reciprocal gene effects. [41] [42] The leopon is a hybrid between a lion and leopard. [43]
