<span><em><u>B. species.</u></em> </span> The organismic hierarchy of organism comes from the highest and lowest order as the following; <span>1. D Domain</span><span><span> 2. </span>K Kingdom</span><span><span> 3. </span>P Phylum</span><span><span> 4. </span>C Class</span> <span>5. O Order</span><span><span> 6. </span>F Family</span><span><span> 7. </span>G Genus</span> <span>8. S Species</span>
This hierarchy and order helped many taxonomist to determine and classify organisms by a variety of criteria. And it seems that <em>species </em>can breed the same fertile offspring.
