Answer 1

Answere :

Biological species concept cannot applied to all of three cases : asexual organisms, bacteria and extinct organism.

According to Biological species concept, "species are groups of potentially interbreeding populations that are reproductively isolated from other such groups."

Is the most widely used and accepted definition of a species, but cannot be applied to Bacteria, asexual organisms and extinct organism.

Bacteria reproduce asexually and asexual reproducing organisn cannot interbreed or mate.  So, it does not apply to both bacteria and asexual reproducing organisms.

Biological species concept is mostly limited to living species where we can observe interbreeding. It does not apply to most fossil species or extint organisms.
