Question

The serial management of taxa is known as
A.Natural Classification
B.Keys
C.Hierarchy
D.Taxonomy

Answer 1

Hint: Taxon, plural is Taxa, is any unit used in biological science for classification, or taxonomy. Within a species, there are a lot of terms for naming genetically controlled variants but they are not considered as taxa. There are mainly seven taxonomic ranks. They are named as Kingdom, phylum or division, class, order, family, genus, species.

Complete answer:
Let’s discuss the given options and find out the correct answer.
-Natural system of classification involves grouping of organisms based on their alikeness and then identifying those properties which are shared by them. It takes a whole lot of characters into account. The most important natural system of classification was given by Bentham and Hooker. It was for seed plants.
-Biological keys are a kind of statements which act like clues helping in the identification of an unknown organism. Systematists completely rely on keys to identify an organism and determine if they have found a completely new organism.
-Different organisms are arranged in successive levels of biological classification either in increasing or decreasing order, the highest level being Kingdom and the lowest bee Species. This classification is called Hierarchy.
-Taxonomy was earlier called systematics. It includes all plants, animals , micro-organisms in this world. Scientists looked at each of the similar properties of the organisms.
Hence, option C: Hierarchy is the correct answer.

Note: Hierarchy is the taxonomic arrangement of living organisms in consecutive levels of complication. The highest rank is Kingdom whereas the lowest rank is Species in this classification.
