(N/A) Taxonomic categories are the distinct levels in the hierarchical classification of organisms.
$1$. Species: $A$ group of individual organisms with fundamental similarities capable of interbreeding. Example: $Mangifera$ $indica$ (Mango).
$2$. Genus: $A$ group of related species which has more characters in common in comparison to species of other genera. Example: $Panthera$ (includes lion and tiger).
$3$. Family: $A$ group of related genera with still less number of similarities as compared to genus and species. Example: $Felidae$ (includes cats and leopards).
$4$. Order: $A$ higher category,being the assemblage of families which exhibit a few similar characters. Example: $Carnivora$ (includes $Felidae$ and $Canidae$).
$5$. Class: This category includes related orders. Example: $Mammalia$ (includes orders like $Primata$ and $Carnivora$).
$6$. Phylum: Classes comprising animals like fishes,amphibians,reptiles,birds,and mammals constitute the next higher category called Phylum. Example: $Chordata$.
$7$. Kingdom: The highest taxonomic category which includes all organisms that share a set of distinguishing common features. Example: $Animalia$.
