Do omnivores necessarily outlive carnivores or herbivores?

From the principle of survival of the fittest, omnivore populations are more viable because they have abundant food**. Pure herbivores or carnivores, on the other hand, are less capable of surviving.

But if it is said that the lifespan of an individual is mainly determined by its reproductive ability. In general, animals will gradually die after losing their fertility due to aging. And the more offspring you have at a time, the shorter your lifespan. It doesn't matter what you eat.

For example, omnivorous cats and dogs live a little over 10 years, while elephants can live more than 60 years on pure grass. Because cats and dogs can give birth to one at a time, it is relatively rare for an elephant to give birth to two.

Not necessarily. The lifespan of an animal depends mainly on the size of the individual, and it is also related to the size of the brain, and has no direct relationship with the type of food, but from the principle of survival of the fittest, omnivores have a stronger population viability. Examples:

Rats are omnivores, but they have a much shorter lifespan because they are much smaller than pure herbivorous elephants. "However, rats are more survivable than elephants--- everyone on earth knows it! >

Omnivorous, herbivorous, and carnivorous are their food**, and food** can affect the continuation of a species or not, and in terms of individual lifespan, the choice of food is only a factor. Rats are omnivorous and do not live as long as grass-fed cattle. The feeding habits are inherited, and the life of an individual depends more on genes and the living environment.

Because the meat of carnivores has a very poor taste, special firewood, and a particularly long cooking time, humans do not eat the meat of carnivores.

No, because these carnivores had some difficulty in the process of domestication, and these habits have not been handed down.

This is part of the reason, because such animals are very ferocious, so such meat is difficult to obtain, ** particularly expensive, and the meat quality is not particularly good.

Herbivores: Animals that live solely on plant tissues. It encompasses a wide range from insects to large mammals, but the term most commonly refers to ungulate mammals.

Adaptations to plant-based food macrophytes include the four-chambered stomach of ruminants, the growing incisors of rodents, and the specialized grinding molars of cattle, sheep, goats, and other bovids.

Carnivores: Commonly known as beefing blue-limbed beasts or carnivores. The teeth are sharp and powerful, with carnivorous teeth, i.e., the last premolar of the upper jaw and the first molar of the lower jaw; The two large cusps of the upper fissure and the two large cusps on the outside of the lower fissure act like a guillotine when biting, which can cut the ligaments and cartilage.

The large teeth are unusually thick, long and pointed, quite sharp, and play a puncture role.

Omnivores: Among mammals, there are many categories that are omnivores.

In fact, most animals are able to go without food for long periods of time, especially cold-blooded animals, and can absorb heat from their surroundings.

And a few warm-blooded animals can also last for a long time by relying on the accumulated fat. Obviously, there are no two ways to store energy, so you need to replenish your energy every day.

This is due to the digestive function of animals, no one's digestive function is so sensitive, and the body structure of some animals makes the lead completely different from the core, so there will be such a long time without eating.

This is due to the fact that the digestive system of humans and other animals is different, and carnivorous animals are able to withstand relatively long feeding cycles.
