Deterring signals: Tobacco plants advertise their defensive readiness to attacking leafhoppers
Following herbivory, plants produce jasmonic acid, a hormone which activates several plant defense reactions. Scientists found that leafhoppers can evaluate whether tobacco plants are ready for defense when attacked. If jasmonate-signaling ...

Herbivore
Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs[page needed] such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers. Comes from the Greek suffix "vora" (Greek -βόρα) meaning "which eat".[citation needed]
Herbivory usually refers to animals eating plants; fungi, bacteria and protists that feed on living plants are usually termed plant pathogens (plant diseases),and microbes that feed on dead plants are saprotrophs. Flowering plants that obtain nutrition from other living plants are usually termed parasitic plants.
A herbivore is not the same as a vegetarian, a human who voluntarily undertakes a primarily herbivorous diet.
