Question

The smallest unit of classification is known as
A. Species
B. De condole
C. Linnaeus
D. Mayr

Answer 1

Hint: Taxonomy is the classification of organisms. It is the identification, nomenclature, description and classification of organisms. It is the study of naming, arranging, classifying, and describing organisms into groups and levels. It has eight ranks called domain, kingdom, phylum, class, order, family, genus and species. Taxonomy is the classification for all the animals, birds and plants. Biological classification is based on the structure, development and evolution history of the species.

Complete answer:
Option A: Family, class and genus come under the higher class in classification; species is the smallest and basic unit of classification. So the species is called the smallest unit of classification. Species is the group of organisms that reproduces naturally with others and creates offspring. Option A is correct.
Option B: De Condole is the botanist who classifies the plants and describes the morphology. He proposed the study of geographical distribution of plants. He introduced new methods of investigation and analysis of photo geography. Option B is incorrect.
Option C: Linnaeus is called the father of modern taxonomy. He discovered the genera and species of organisms. He created the uniform naming for the organism. This is called binomial nomenclature. His theory is based on the similarities in physical traits. Option C is incorrect.
Option D: He proposes the biological species concept. His works are based on the species and speciation so it helps to understand progress and mechanism of evolution from species to species. Option D is incorrect.

Hence, Option A is the correct answer.

Note:
Species are the groups of actual or potentially interbreeding natural populations. It is reproductively isolated from other groups. Species are the integral component of the ecosystem and finding the value of species in the ecosystem is still unknown or can't be found. Biodiversity is an important thing for humans because it supports ecologically. Biodiversity provides a functioning ecosystem and it supplies oxygen, clean water, clean air and many ecosystem services.
