A niche is defined as a specific area, where an organism lives and interacts with all the abiotic and biotic factors that affect it.

Hence, one of the two competing species gets evolved to use a different niche and uses different sources. This is known as resources partitioning and helps the organisms to coexist by reducing competition between them.
