Tasmanian devils eat possums
Dingoes do not eat Tasmanian devils. There are no dingoes on the Australian island of Tasmania, and there are no Tasmanian devils remaining on the Australian mainland. When the two species co-existed on the mainland, scientists do not believe that dingoes took on Tasmanian devils as predator to prey, but that the two species were competitors for food.
Humans should save Tasmanian Devils because they eat the sick and dead animals.
No. Although both carnivorous mammals, this is where the similarity between Tasmanian devils and dingoes stops. Tasmanian devils are marsupials, with a pouch in which they rear their young. Dingoes are relative "newcomers" to Australia, and placental mammals.
If there were stoat in Tasmania, which there are not, it is likely that the Tasmanian devil would eat them, if the opportunity arose. Tasmanian devils favour small mammals, but the stoat could possibly be too quick and fierce to be caught.
No. Tasmanian devils are marsupials.
dingos and people
No. Tasmanian Devils eat carrion, which means the dead bodies of animals, as well as live prey which is small, such as up to the size of a wallaby. They would not and could not eat a human being.
Of course Tasmanian devils breed. If they didn't, there would be no Tasmanian devils left today. Tasmanian devils are mammals, which are vertebrates. All vertebrates breed.
