The data collected on the bacterial species in the Yellowstone national park involved:
1. habitat characteristics
2.DNA of bacteria from each population
3. compared with other species of the park
Based on these features, the biologist could apply all the types of species concept like ecological species concept which allows the study of the species from the same niche.
Also, they compared the DNA of the species of the bacteria and compared them which allows to trace the evolutionary patterns and showing the phylogenetic relationship.
Since bacteria do not reproduce by the sexual reproduction, therefore, a biologist cannot apply the biological species concept which states that species can be called species which can reproduce only with the closely rated species only or the individual of the same species.
Thus, Option-B is the correct answer.
Microscopic particles are called atoms.
