According to most ecologists, herbivores should be considered predators because they eat (prey upon) another living organisms, in this case plants.
The following is from Wilson and Bossert (1971, p. 127):
....ecologists define predation in its broadest possible sense: the eating of live organisms, regardless of the identity of the organism. Predation includes the consumption of plants by animals, called herbivores....
Koalas are just prey. Koalas are herbivorous, feeding primarily on eucalyptus leaves and blossoms, so they are not predators. They may fall prey to dingoes, domesticated dogs and foxes.
No. They are herbivorous, just like their horse and donkey counterparts.
Predators to a rabbit, is well, practically everything! And Rabbits are herbivorous, they only eat grass and weeds in the wild.
NO. Just like with all other horses, Mongolian wild horses are prey animals, or herbivorous. They are not predators: predators eat meat or have an omnivorous (plant and meat) diet.
Rhinoceroses are herbivorous and therefor eat no meat. Thus, they are not predators of any animals. They do eat a variety of plants, such as grasses and shrubs.
Mollusks eat all kinds of things. The cephalopods (octopii, squids, and their allies) are predators of fish and other marine life. Most bivalves are pretty much herbivorous, feeding primarily on algae, though some are predators. The gastropods are also mixed, with some herbivorous, such as abalones, and some carnivorous predators, such as moon snails, oyster drills, and cone shells. Incidentally, some cone shells (Family Conidae) are poisonous enough to kill people!food

Possums are generally not regarded as predators. There are some species of possums which are omnivorous, eating bth plant parts and insects, but many species are herbivorous.
The three toed sloth is herbivorous except that it eats some insects. The two toed sloth is mostly herbivorous too, but they also eat insects, and even small vertebrates if they manage to catch them.
Herbivorous dinosaurs, excluding ankylosaurs and stegosaurs, probably fled from predators whenever possible, but would have fought when cornered. Ankylosaurs and stegosaurs were very slow, so they would have stood their ground, using their spiked or clubbed tails as weapons against predators. Some herbivorous dinosaurs, including ceratopsians and pachycephalosaurs, may have fought others of their species over mates.
