Question

A group of organisms belonging to the same order on classification also comes under
(a) Genus
(b) Class
(c) Species
(d) Family

Answer 1

Hint: Orders Rodentia(rats), Chiroptera(bats), Cetacea(whales), Carnivora(dogs), Primates(monkeys, apes, gorillas, gibbons, and humans), etc. belongs to the category where one or more of these forms a phylum.

Complete answer:
The taxonomic hierarchy includes seven categories namely kingdom, phylum, class, order, family, genus, and species. Class is the category of an organization that includes one or more related orders. For example, The class Mammalia includes the orders Rodentia(rats), Chiroptera(bats), Cetacea(whales), Carnivora(dogs), Primates(monkeys, apes, gorillas, gibbons, and humans), etc.

Additional Information: - Taxonomic hierarchy includes seven categories namely kingdom, phylum, class, order, family, genus, and species and other intermediates categories such as subkingdom, grade, division, subdivision, subphylum, superclass, subclass, superorder, suborder, super Family, subfamily, subspecies, etc.
- Kingdom Animalia or metazoa include all multicellular, non-saprobic, heterotrophs
- One or more classes are included in the category phylum. For example phylum, Chordata includes the classes Cyclostomata, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia.
- One or more related orders are included in the category class
- Assembly of one or more related families is in the category order. For example, Felidae and Canidae are included in the order Carnivora along with Hyaenidae(hyenas), Ursidae(bears), etc.
- One or more related genera forms a family and a group of related species forms a genus and the similar organisms that share a common gene pool are in the category species. Family Felidae includes a genus of the cat(Felis), a genus of leopard(Panthera), etc
- The category class is subdivided into superclass and subclass.
So, the correct answer is 'Class'

Note: The first taxonomist to establish a hierarchy of taxonomic categories called taxa is Linnaeus. It includes taxa like kingdom, class, order, genus, and species. Haeckel in 1888 introduced the taxon phylum.
