Answer 2

Answer:

Canis doesn’t belong to the same level of taxonomic hierarchy as that of lupus, nigrum, and aestivum.  

Explanation:

In a taxonomical hierarchy,

• Canis – Falls under ‘Genus’. Canis belongs to kingdom Animalia/Phylum-chordata/Class-Mammalia/Order-Carnivora/Family-Canidae/Genus-Canis that refers to animals like dogs, wolf, fox.
• Lupus- Falls under ‘Species’. Lupus is a species name that belongs to Genus Canis, like Canis lupus - a type of wolf.  
• Nigrum - Falls under ‘Species’ nigrum is a species of Genus Solanum, like Solanum nigrum – nightshade plant
• Aestivum - Falls under ‘Species’ aestivum is a species of Genus Triticum, like Triticum aestivum- wheat plant

     Taxonomic hierarchy arranges living organisms based on their group, class, and other criteria and categories into successive hierarchical levels.

     This biological classification is ranked from the highest to lowest in the following order: Kingdom/division/class/order/family/genus/species.
