Which of the following correctly represents a taxonomic hierarchy in descending order?

Kingdom → Phylum → Class → Order → Family → Genus → Species
Kingdom → Class → Phylum → Order → Family → Genus → Species
Species → Genus → Family → Order → Phylum → Class → Kingdom
Kingdom → Phylum → Family → Order → Class → Genus → Species
1

The correct descending taxonomic hierarchy is: Kingdom → Phylum → Class → Order → Family → Genus → Species.

What makes species the most fundamental unit of classification?

Species share similar genetic makeup and can interbreed
Species are the largest taxonomic unit
Species are ranked above the genus level
Species have no common features
1

A species consists of individuals that share a similar genetic makeup and can interbreed to produce fertile offspring.

Which taxonomic category ranks higher than Order but lower than Phylum?

Species
Class
Genus
Family
2

Class is a taxonomic category higher than Order but lower than Phylum.

Which scientist is associated with the binomial system of nomenclature?

Ernst Mayr
Charles Darwin
Carolus Linnaeus
Gregor Mendel
3

Carolus Linnaeus introduced the binomial system of nomenclature, which is still used today.

Which taxonomic category is directly ranked below Order?

Species
Genus
Family
Class
3

Family is ranked directly below Order in the taxonomic hierarchy.

What is the taxonomic rank of Panthera tigris?

Genus
Species
Family
Phylum
2

Panthera tigris is a species, where "Panthera" is the genus and "tigris" is the species name.

Which of the following taxonomic ranks is common to both plants and animals?

Division
Phylum
Class
Family
3

Class is a taxonomic rank common to both plant and animal classification.

Why is binomial nomenclature considered more scientific than common names?

It uses two names to uniquely identify a species
It allows multiple names for the same organism
It is based on local language preferences
It replaces taxonomy with common terms
1

Binomial nomenclature assigns a unique and universally accepted name to each species, avoiding confusion caused by common names.

Which of the following statements is TRUE about taxonomic hierarchy?

Higher taxonomic categories have more similarities among members
Lower taxonomic categories have more similarities among members
Genus is broader than Family
Phylum is the most specific category
2

Lower taxonomic categories, such as Species and Genus, have more similarities among members compared to higher categories.

How does classification help in studying biodiversity?

It groups organisms based on their genetic differences
It helps identify relationships between different species
It focuses only on external morphology
It categorizes only known species
2

Classification helps in understanding biodiversity by identifying relationships between different species based on their characteristics.
