residual within an ecosystem occurs through a close descent amid two species. This relationship called symbiosis is categorized into trey main categories; mutualism, commensalism and parasitism. Commens alism usually occurs between a species that ! is either endangered to depredation or with an inefficient means of locomotion, and another species with a relatively effective system of defense. In a parasitic relationship, the forces species is always exploited to some degree, although often in such a way that its health is impaired only slowly.
