Apparent competition can occur when two species share a predator.

This gave them a great advantage over the other groups wherever open competition occurred.

The annual competition began in 1984 and occurs in July of each year.

The competitions for both men and women occur at the same venue.

Such competitions have occurred as a way of raising money for charity.

The competition has occurred every two years since 2006, always in the capital of Germany.

Since only one row is selected at a given time, no competition for the output line occurs.

The competition has since occurred biennially in 2005, 2007, 2009, and 2011.

The head-to-head competition occurred in front of a live studio audience.

Events and competitions leading up to the event occur throughout the period between festivals.
