Do all organisms fit equally well under the biological species concept? Explain.
What will be an ideal response?
The biological species concept is appropriate for species that use sexual reproduction, so that it can be determined whether or not individuals from two different groups interbreed. This concept works less well with creatures, like bacteria, some protists and fungi, and a number of plants, that reproduce asexually all or part of the time. The biological species concept is now employed for animals, but not so much for members of the other kingdoms.
