In ecology, predation describes a biological interaction where a predator organism feeds on another living organism or organisms known as prey. Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the (ecologically significant) death of the prey. The other main category of consumption is detritivory, the consumption of dead organic material (detritus). It can at times be difficult to separate the two feeding behaviors, for example where parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on its decaying corpse. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat what is available and have no direct impact on the 'donor' organism(s). |

A sniper is an infantry combatant or serviceman (e.g. police officer) who specializes in shooting from a concealed position over longer ranges than regular infantry, often with a specially designed or adapted sniper rifle. A sniper requires skill in marksmanship, camouflage, and field craft. Military snipers are also adept at carrying out methods of infiltration, reconnaissance, and observation techniques.
