Question

In the following line diagram showing taxonomic hierarchy of plants, identify the missing taxonomic unit.​

Division $\to$ Class $\to$ Family​

Answer 1

Correct option: (a) order.​

Order is the missing taxonomic unit in the given diagram.​

The arrangement of various taxa in a hierarchial order is called taxonomic hierarchy. In this hierarchy, species is present at the lowest level whereas kingdom is present at the highest level. Between kingdom and species, there are various levels.​

At each level, plants are grouped based on their similarities. Related species are grouped together to form a genus, related genus as family, related family as order, later class, division and kingdom. Hence the correct taxonomic hierarchy is :-​

Division $\to$ Class $\to$ Order $\to$ Family​
