does any other animal change from omnivore to herbivore to carnivore.....?

Question

what i mean is would a lion stop hunting zebra if they got fewer or would they eat them to extinction then move on to the next animal or would they eat vegitaion if they were biologialy capable.do animals have morals on thier diets like some humans do

Answer 1

animals live by instinct. they would change thier diet if one food stuff runs out, but thier biology wouldn't change.

As we all know, animals could live on a veggie diet but not a meat diet. So if thier prey is not available they can quite easily survive indefinately on a vegetarian diet, just like humans.

I think a lion would eat zebra to extinction. Humans claim to be more intellegent but we'd do the same thing if the laws didn't stop us ( fish, panda, bear etc ).

Answer 2

It depends. Some animals are capable of adapting to their diet according to what is available. In your example about the lions, they would not hunt zebras to extinction unless that was the only food source available, and in a natural habitat that is unlikely to happen. Lions do not necessarily single out a particular type of animal, but will eat what is available. If there were no animals available to eat (which would be a very strange, unhealthy ecosystem at that point), they might start eating vegetattion out of desperation. However, they would not be able to survive for long on such a diet as lions are obligate carnivores, meaning that they need meat to survive, and can survive on a diet consisting solely of meat.

Omnivores, on the other hand, are more flexible: they can eat both animal and vegetable material. Humans are omnivores. We can survive quite nicely without meat, but our bodies can also process it for nutrients as well (though an excess will lead to disease).

It is most likely that animals do not have the higher brain functioning that would allow them to consider the ethics of their diets. Even if they did so, not all of them would have the option to omit meat out of their diets due to a lack of plant variety available in their habitat. Humans, on the other hand do have the thought processes that allow them to have compassion and choose more compassionate foods. Many of us are alos very lucky to be in a position where we have enough plant material of a great enough variety available to us so that we can meet our nutrient needs. Given that, some of us choose to consume plant-based diets to help prevent animal suffering. A plant based diet is also better for the environment and your health.

Answer 3

Carnivore to Herbivore
A graveyard of feathery dinosaurs in Utah shows signs of carnivores adapting to a more leafy diet, paleontologists say.
The recently discovered species of dinosaurs, called Falcarius utahensis, had legs built for speed like meat-eaters but it also had a wide pelvis designed for the longer gut common in vegetarian animals that ferment plants.

The creature was 1.4 metres tall and about four metres long from nose to tail. It walked on two legs about 125 million years ago, as flowering plants were evolving.

Falcarius had wooly, feather-like hairs, sharp, curved claws and teeth suited for shredding leaves, rather than cutting apart meat. Scientists don't yet know whether it ever had a hankering for flesh.

Paleontologist James Kirkland of the Utah Geological Survey and his colleagues unearthed the mass graveyard of 2,000 bones at the Cedar Mountain formation south of Green River.

The find helps researchers to fill in gaps in their understanding of plant-eating Therizinosaurs that evolved from meat-eaters

Therizinosaur (pronounced THAY-rih-ZY-no-sores) were mainly found in Asia, but their fossils are scarce. It's thought they evolved from two-legged predators called theropods, but their closest cousins were raptors like the Velociraptors of Jurassic Park fame.

Falcarius and Velociraptors shared a common, yet-undiscovered ancestor, said study co-author Scott Sampson, a paleontologist and curator at the Utah Museum of Natural History.

"With Falcarius, we have actual fossil evidence of a major dietary shift, certainly the best example documented among dinosaurs," Sampson said in a release. "This little beast is a missing link between small-bodied predatory dinosaurs and the highly specialized and bizarre plant-eating therizinosaurs."

No one knows what killed off the buried dinosaurs, but scientists say drought, volcanic eruptions, fire and botulism poisoning are all possibilities.

The find is described in the May 5 issue of the journal Nature.

Answer 4

Animals will eat what they are biologically programmed to eat. And cats put on a vegetarian diet will go blind. They need the taurine found in animal proteins.

Answer 5

no, no animal will change its eating habbits unless it metamorphises and no, animals live by instinct not moral values.
