Interspecific competition is a competition between two species for obtaining the same resource. For example, lion and leopards are cat species but feed on the same prey so they compete for the same resource.
Interspecific competition may lead to resource partitioning through the change in their niche by one species to avoid interspecific competition.
For example, <em>Anolis evermanni</em> and <em>Anolis gundlachi</em> are two species of lizards live on Puerto Rico island and compete for the same resource i.e., insects so to avoid interspecific competition they did the resource partitioning.
Anolis gundlachi feeds near the ground and Anolis evermanni prey on upper branches of trees so in this way they avoid competetion.
