It is Intra and Interspecific - the latter being among individuals of different species, the former being among individuals of the same species. You can also have direct and indirect competition within Intra and Interspecific competition.

So, for example, in interspecific: Two species of fish which compete for the same food resources in a pond; or two species of warbler that eat the same type of caterpillars.

Intraspecific: Two oak trees growing next to each other competing for light, water, nutrients, etc. Or a colony of diamondback rattlesnakes living in the desert competing for food.
