1 A detritivore such as the millipede is an herbivore that eats decaying plant material. 2  Millipedes have four legs per body segment; centipedes have two.  Millipedes are slow-moving herbivores. Centipedes are fast-moving carnivores; they're often brightly colored to warn predators of their venom.
A herbivore is often defined as any organism that eats only plants. By that definition, many fungi, some bacteria, many animals, about 1% of flowering plants and some protists can be considered herbivores. Many people restrict the term herbivore to animals. Fungi, bacteria and protists that feed on living plants are usually termed plant pathogens. Microbes that feed on dead plants are saprotrophs. Flowering plants that obtain nutrition from other living plants are usually termed parasitic plants.
