Is an ostrich a scavenger

Answer 1

Recent theories now believe it may have been a scavenger, because of its weight, might not could have been quick enough to catch its prey, also, the teeth are for bone crushing, like a scavenger. Its sense of smell was acute, similar to modern vultures. So T Rex may not have been a great hunter, but like the hyena, might have done a little of both. The reasons to believe they were predators and scavengers are pretty obvious: 1. First thing is proof. A skeleton of a large plant eating dinosaur called Edmontosaurus was discovered and was missing one of its vertebrae. The vertebrae had a tooth mark in it that matched exactly that of T-Rex's tooth. Also the vertebrae showed evidence of healing , which tells us that the Edmontosaurus had escaped, and that the T-Rex had attacked it in an attempt to bring it down. 2. It's arms however were useless. A predator needs its front limbs for grabbing its prey. T. rex could not do that. However many paleontologists think the reason the arms of Tyrannosaurs got smaller and smaller while the head got bigger and bigger, was so that it could evolve a powerful jaw which was its main weapon in killing prey. 3. It weighed 6-7 tons. If it fell over, it would die, because it couldn't push itself up again (due to its useless arms and its crushing mass). It was probably an ambush predator however and did not chase prey once it had been spotted. 4. It was slow. Because of its size and the proportion of its leg bones (the bones in its leg are roughly the same size, like a human's, making it a pretty slow runner, unlike, say, an ostrich, which has long lower leg bones, a characteristic common to all fast runners), it couldn't get up to speed, so probably couldn't run down prey, but could ambush large slow moving prey. 5. No animal is going to pass up a free meal, so just about any meat eating animal probably scavenged. This does not make it 100 percent scavenger. An animal as big as T-Rex could not survive on scavenging alone. If it did it would pretty much have to depend on other carnivores to make kills, and an animal this big need to eat a lot. It isn't guaranteed that other carnivores will have made a kill every time a T-Rex needed to eat, therefore T-Rex would have to find prey of its own. 6. It's teeth and head muscles are unparalleled by other dinosaurs. The amount of force that a T. rex could exert with its jaw muscles was extraordinary, perfect for crushing bones and consuming all parts of a dead animal. Such musculature could be found in predators as well, so obviously T-Rex had evolved a different method of killing prey rather than having a slashing bite like most big carnivores. All that being as it may, science is a search for facts, not truth. New evidence may show up that totally refutes the argument for T. rex being a scavenger, or the facts may be interpreted differently by different people. Science is always changing, always looking to disprove itself. The evidence is strong that T. rex was, in fact, a predator, as well as a scavenger, but the "truth" of the matter is that we will never know for sure.

Answer 2

Kangaroos are not scavengers. The vast majority of species are herbivores, feeding on grasses and leaves. Some of the smaller species are omnivores, eating roots, tubers, fungus and arthropods, but none of them are scavengers.

Answer 3

No. crocidiles hunt for their food and kill their prey by taking it into a death roll or biting with their teeth

Answer 4

yes because he goes looking for food,they don't stand and wait.

Answer 5

An Alligator is a Predator because they eat other animal.

Answer 6

Yes,ostrich is a scavenger .
