One of the classifications The most common thing that is made of animals is with respect to their food source, and divides them between carnivores, herbivores and omnivores. For instance: lion, deer, cod.
East behaviour it does not respond to the preferences of animals to eat one thing before the other, but is often due to characteristics of their physical build or the environment in which they must live.
The carnivorous animals they are those that feed on other animals, which already indicates some questions related to their characteristics and behaviors. They are, in general, aggressive animals prepared for attack, so their body must adequately combine agility with strength.
Also, as the dam Of the carnivores it must be transformed until it is taken to the state in which it is edible, carnivores always have teeth with a series of highly developed fangs, which allow killing the prey.
Frequently a division of carnivores into two large groups:
- Predators. They are the ones who hunt their prey and then devour it, developing the adaptations that allow them to carry out their hunt through the senses of smell and taste;
- Scavengers. They feed on animals that are already dead. The latter have a substantial contribution to the ecosystem since they eliminate organic remains that do not serve the earth.
Examples of carnivores
|Egyptian vulture||Tasmanian devil||Jackal|
|Lion||Black vulture||Lion wolf|
|Ant Soldier||Andean condor||Meat fly|
|Killer whale||Alligator||Common Vulture|
|Dingo||Marine Anguilla||Polar Bear|
|Ghoul beetle||Porcupine||Giant ant|
|Black Panther||Hyena||White shark|
The herbivorous animals they are those that feed exclusively on plants, and do not have the body prepared to eat meat. In this way, if the carnivores were prepared to kill their prey and then eat it, the herbivores do not need either of these two actions: at most they are prepared for the defense of the carnivores.
Refering to teeth, It must not be so strong or sharp to transform an animal into food, but on the contrary it needs to have incisor and molar teeth with the function of cutting, shredding and grinding the vegetable well.
Like carnivores, herbivores also have an internal classification:
- Ruminants. They have legs adapted for running since they are exposed to different predators, and are characterized by swallowing a lot of food in a short time and then grinding it to digest it.
- Simple stomach herbivores. That they eat habitually of soft stools;
- Compound stomach herbivores. They obtain their nutrients through waste produced by microorganisms when breaking the fibers.
Examples of herbivores
|Cricket||Parakeet||Beef or cow|
|Macaw||Fir beetle||Pleco fish|
|Wildebeest||Pearl Butterfly Fish||Deer|
|Catfish Fish||Weevil||Barbel fish|
The omnivorous animals They are the ones that can eat both vegetables and meat from other animals, that is, they are characterized by being nourished by all kinds of foods. These are the only ones who sometimes have the possibility to choose, although in most cases they feed on what they get when the occasion comes.
The ability to feed on both animals and vegetables gives omnivores a great advantage since they can survive in any environment, which does not happen in other animals that have a more specialized diet. Here are some examples of omnivores.
