competition

Competition is, in general, a contest or rivalry between two or more entities, organisms, animals, individuals, economic groups or social groups, etc., for territory, a niche, for scarce resources, goods, for mates, for prestige, recognition, for awards, for group or social status, or for leadership and profit. It arises whenever at least two parties strive for a goal which cannot be shared, where one's gain is the other's loss (a zero-sum game).
Competition occurs naturally between living organisms which co-exist in the same environment. For example, animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and fame.
Competition is often considered to be the opposite of cooperation, however in the real world, mixtures of cooperation and competition are the norm. Optimal strategies to achieve goals are studied in the branch of mathematics known as games theory.
Competition is also a major tenet of market economies and business It is often associated with business competition as most companies are in competition with at least one other firm over the same group of customers. Also competition inside a company is usually stimulated with the larger purpose of meeting and reaching higher quality of services or improved products that the company may produce or develop.
