Competition: when two or more organisms need the same resource (food, water, space, territory, mates) for survival

Competition and self-interest are two forces in free market economies.

Oligopolic!

Competition occurs when organisms of the same or different species attempt to use an ecological resource in the same place at the same time.

In perfect competition, quality is homogenous, so false: competition encourages businessmen only to provide products a lower price. Product innovation (aka quality) destroys competition by creating specialisation of a good (also known as monopolistic competition - i.e.) Apple versus Microsoft).
