RISE!
The more producers that have to compete with each other on the market, the more chance there is that each will try to draw any business by lowering its price to the consumer.
Sometimes, questions like this can be solved by imagining the ultimate scenario:
Imagine for a moment that suddenly ALL tennis ball producers closed down except one. That one could ask almost any price for its tennis balls that a large proportion of players was prepared to pay ... the company would have much trouble in managing to cater for everyone anyway - until it had time to expand and meet market demand.
A diagram of a perfectly competitive market typically shows a horizontal demand curve representing perfect competition, a horizontal supply curve at the market price, and a point where supply equals demand to show equilibrium. It also includes the producer and consumer surplus to illustrate market efficiency.
There is no such thing as a perfectly competitive market. It is merely a economic model to compare other market structures to. Cigarette market is more likely a oligopoly.
