You are probably asking what is an 'omnivore'. An omnivore eats plants as well as meat. Omni - all. Vore - devour.
The word "omniver" is used as a shortened version of omniverse, similar to the words universe, or multiverse.
No. They're herbivores.
A hyena is a carnivore and a scavenger of other animal kills.
MOST BUTTERFLIES SURVIVE IN THEIR ADULT STAGE BY DRAWING NECTAR THROUGH A LONG, COILED MOUTHPIECE. some BUTTERFLIES, LACKING THESE MOUTH PARTS, EAT NOTHING AT ALL AND DIE SOON AFTER MATING AND LAYING EGGS. sINCE NECTAR IS A PLANT JUICE, MOST BUTTERFLY SPECIES WOULD BE CLASSIFIED AS HERBIVORES.
