Organisms are the same species if the have the potential, or actually interbreed one with another. Does not apply to all organisms. Bacteria being an example of this. Is not as strong a concept as once it was as it did not adequately address hybridization.
Ernest Mayr is the modern author of what he called the biological species concept, but the idea has been in the literature for over two centuries. The earliest published author of whom I am aware is Johann F. Blumenbach, in 1775 in his On the natural varieties of mankind, although he cited "the sagacious Frisch" as the originator of the view, and even John Ray, who first defined biological species: "After long and considerable investigation, no surer criterion for determining species has occurred to me than the distinguishing features that perpetuate themselves in propagation from seed" in his Historia plantarum generalis, 1686. This is not a "biological" conception. Also, Linnaeus implicitly used a "biological" conception of species too, later in his life, in the Systema Vegetabilium.
The name "biological species concept" was contrasted with "morphological species concept" as used in museums, by Mayr. However, all concepts of biological species are biological concepts, and it is better called a "reproductive isolation species concept", since that is what it differs from other concepts in.
The actual or potential interbreeding of conspecifics in populations. A biological species can actually or potentially interbreed with a member of the same species.
being able to interbreed and produce fertile offspring
That organisms are of the same species if they can potentially, or actually breed with each other.
Species are populations that interbreed and produce fertile offspring

No, biological species concept is NOT useful for extinct organisms at all, nor organisms that reproduce asexually; it is only useful for organisms that produce sexually.
There are two main problems that can be identified in the biological species concept. This concept emphiasizes interfertility between organisms. However, reproductive barriers between sexual reproducing species are not always effective. Sometimes, individuals of different species interbreed and produce offspring call hybrids. Also this concept fails to describe species that are predominantly asexual in their reproduction, including all bacteria as well as some protists, fungi, plants, and even a few animals.

Biological species concept, phenetic species concept, reproductive competition species concept, evolutionary species concept, and the recognition species concept.
Biological species concept :)
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.

interbreeding capabilities
Can mate with other individuals of their species and have viable progeny.
