Various kinds of animals eat several types of meals: carnivores eat meat, herbivores eat vegetation, and omnivores eat each vegetation and meat. Examples of animals with extra specialised diets embody fructivores (fruit eaters); and folivores (leaf eaters).
On this web page you’ll discover details on carnivores, omnivores and herbivores, plus many examples of extra specialised animal diets.
Web page Index
All organisms, be they animal, plant, fungus, and even single-celled lifeforms corresponding to micro organism, want the vitamins contained in meals with a view to stay.
Vitamins present an organism with each vitality and materials from which new cells might be made.
With out meals, an animal wouldn’t have the vitality required to breathe and transfer, or the fabric required to develop, restore itself or reproduce.
Autotrophs Vs Heterotrophs
Organisms corresponding to vegetation are autotrophic, which signifies that they produce their very own meals.
Vegetation do that through photosynthesis – a course of during which vitality from the solar is changed into meals.
Yow will discover out extra about photosynthesis on this web page: Photosynthesis Information
Animals are heterotrophs. Heterotrophic organisms are unable to provide their very own meals, subsequently should devour natural matter (both dwelling organisms or the stays of dwelling organisms) to get the vitamins wanted for all times.
Even herbivorous (plant-eating) animals corresponding to rabbits are heterotrophs, as they devour vegetation, that are natural.
An animal is described as being both a carnivore, herbivore or omnivore relying on the kind of meals it consumes.
- Carnivore = meat eater
- Herbivore = plant eater
- Omnivore = eats meat and vegetation
All animals – even carnivores – are reliant on autotrophs corresponding to vegetation or algae; though carnivores don’t eat vegetation themselves, their prey does!
Yow will discover out extra in regards to the relationship between vegetation and several types of animals on this web page: What Is An Ecosystem?
Beneath, we have a look at these three foremost sorts of animals, then check out extra specialised eaters, together with folivores (leaf-eaters), frugivores (fruit-eaters) and animals that observe coprophagy (you don’t wish to know!).
What Do Animals Eat – Carnivores
A carnivore is an animal that eats different animals. Carnivores are also called meat-eaters.
Predators are carnivores that hunt prey; scavengers are carnivores that eat carrion (the stays of animals).
An apex predator is a predator that has no predators of its personal. Examples of apex predators embody the tiger and the killer whale / orca. You’ll be able to see extra examples of apex predators on this web page: Apex Predators
The ancestors of all amphibians, reptiles, mammals and birds have been carnivores. All of those animal teams belong to group of vertebrates generally known as tetrapods. The primary tetrapods have been amphibious, piscivorous (fish-eating) animals.
Each the earliest reptiles, and the earliest mammals, are thought to have been insectivores (insect-eaters). Paleontologists use varied clues, corresponding to the form of a fossilized animal’s enamel, to inform what meals it ate when it was alive.
Carnivores might be given names relying on the quantity of meat they devour. Hypercarnivores have a eating regimen consisting of over 70% meat; the eating regimen of mesocarnivores consists of 30–70% meat, and hypocarnivores eat lower than 30% meat. (Mesocarnivores and hypocarnivores may additionally be referred to as omnivores.)
Obligate carnivores are animals (corresponding to cats) that require vitamins solely present in animal flesh, and are unable to interrupt down plant matter.
Predatory carnivores have variations corresponding to energy, pace, forward-facing eyes, sharp enamel and talons or claws for catching prey.
Diversifications of scavengers embody an acute sense of scent for finding meals, tough enamel or claws for tearing meals aside, and a sturdy digestion for breaking apart bones and / or rotting meat.

What Do Animals Eat – Herbivores
Herbivores are animals whose eating regimen consists totally or primarily of vegetation. Plant materials is usually powerful and fibrous, containing comparatively little vitality.
Due to this fact, herbivores require specialised variations with a view to acquire the required vitamins from vegetation.
Rodents have enamel that constantly develop (and subsequently by no means put on down); cattle and plenty of different hooved animals have multi-chambered stomachs and regurgitate their meals as cud for additional chewing with a view to get enough vitamin from their powerful, low-energy meals.
Herbivores which are prey animals have traits corresponding to acute senses for detecting predators, and pace and agility for escaping from predators.
You’ll be able to see examples of herbivores on this web page: Examples of Herbivores
What Do Animals Eat – Omnivores
Omnivores are animals whose eating regimen consists of each animal and plant materials. Omnivores embody each animals whose ancestors have been carnivores, and animals whose ancestors have been herbivores.
Omnivores are normally much less specialised than both herbivores or carnivores. For instance, omnivorous mammals corresponding to most bears lack the multi-chambered stomachs of hooved mammals. Omnivorous birds, corresponding to crows, lack the talons of birds of prey.

Different Animal Diets
A detritivore is an animal that feeds on detritus (non-living natural matter). Examples of detritivores embody earthworms and millipedes.
