Chemical Defense involves the protection against chemical agents that are harmful to human beings, animals, and the environment.

Quote: "Chemical defense is a strategy employed by many organisms to avoid consumption by producing toxic or repellent metabolites or chemical warnings which incite defensive behavioral changes."
Quote: "The production of defensive chemicals occurs in plants, fungi, and bacteria, as well as invertebrate and vertebrate animals."
Quote: "The class of chemicals produced by organisms that are considered defensive may be considered in a strict sense to only apply to those aiding an organism in escaping herbivory or predation."
Quote: "However, the distinction between types of chemical interaction is subjective and defensive chemicals may also be considered to protect against reduced fitness by pests, parasites, and competitors."
Quote: "Repellent rather than toxic metabolites are allomones, a subcategory signaling metabolites known as semiochemicals."
Quote: "Many chemicals used for defensive purposes are secondary metabolites derived from primary metabolites which serve a physiological purpose in the organism."
Quote: "Secondary metabolites produced by plants are consumed and sequestered by a variety of arthropods."
Quote: "Toxins found in some amphibians, snakes, and even birds can be traced back to arthropod prey."
Quote: "There are a variety of special cases for considering mammalian antipredatory adaptations as chemical defenses."
