An adaptive growth response of plants to herbivory in which removal of plant tissues stimulates the plant to produce new tissues.
crypsis
A defense against predators in which prey species have a shape or coloration that provides camouflage and allows them to avoid detection.
exploitation
A relationship in which one organism benefits by feeding on, and thus directly harming, another.
herbivore
An organism that eats the tissues or internal fluids of living plants or algae.
induced defense
In plant–herbivore interactions, a defense against herbivory, such as production of a secondary compound, that is stimulated by herbivore attack.
mimicry
A defense against predators in which prey species resemble less palatable organisms or physical features of their environment, causing potential predators to mistake them for something less desirable to eat.
parasite
An organism that lives in or on a host organism and feeds on its tissues or body fluids.
parasitoid
An insect that lays one or a few eggs on or in a host organism (itself usually an insect), which the resulting larvae remain with, eat, and almost always kill.
predator
An organism that kills and eats other organisms, referred to as its prey.
secondary compound
One of a wide variety of chemicals produced by plants and used in functions such as defense against herbivory, protection from harmful radiation, and soil nutrient cycling; secondary compounds are so-named because they are synthesized on side branches off of the primary metabolic pathways that produce the carbohydrates, amino acids, lipids, and other compounds common to all organisms.
sit-and-wait predator
A predator that hunts by remaining in one place and attacking prey that move within striking distance.
warning coloration
A defense against predators in which prey species that contain powerful toxins advertise those toxins with bright coloration; also referred to as aposematic coloration.
