How to approach this question
Recall the levels of the Linnaean classification system. A common mnemonic is "King Prawn Curry Or Fat Greasy Sausages". The table shows Phylum, Class, Order, etc. What is the level that comes before Phylum?
Full Answer
C.Kingdom✓ Correct
Kingdom
The Linnaean system classifies organisms into a hierarchy of groups called taxa. The main levels, from broadest to most specific, are: Kingdom, Phylum, Class, Order, Family, Genus, Species. In the table, the first classification group shown is Phylum. The level above Phylum is Kingdom. Since the trilobite is an animal, its kingdom is Animalia.
Common mistakes
✗ Choosing a level that is lower down in the hierarchy, like Genus.
✗ Choosing a term that is not part of the classification hierarchy, like Community or Population.
