Taxonomy & Classification of Organisms

What is taxonomy?

• The study of animal behavior.

• The science of classifying organisms into groups based on similarities and differences.

• A method of measuring biodiversity.

• The process of evolution in species.

What is the role of a taxonomist?

• A scientist who classifies and names organisms based on their characteristics and evolutionary history.

• A scientist who studies the behavior of animals in their natural habitat.

• A scientist who focuses on the chemical processes within living organisms.

• A scientist who researches the effects of climate change on biodiversity.

Who is known as the 'Father of Taxonomy'?

• Carl Linnaeus

• Charles Darwin

• Gregor Mendel

• Louis Pasteur

What is the correct order of the levels of taxonomy (abbreviated) from least to most specific?

• DKPCOFGS (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species)

• DOKPCFGS (Domain, Order, Kingdom, Phylum, Class, Family, Genus, Species)

• DKPFGCOS (Domain, Kingdom, Phylum, Family, Genus, Class, Order, Species)

• DOKPFGCS (Domain, Order, Kingdom, Phylum, Family, Genus, Class, Species)

What characteristics describe organisms found in the domain Eukarya?

• Organelles, DNA in nucleus, 4 kingdoms, autotrophs & heterotrophs

• Prokaryotic cells, no nucleus, 2 kingdoms, only autotrophs

• Single-celled organisms, no organelles, 3 kingdoms, only heterotrophs

• Multicellular organisms, DNA in cytoplasm, 5 kingdoms, only autotrophs

What are the three domains of life?

• Bacteria, Archaea, Eukarya

• Plants, Animals, Fungi

• Prokaryotes, Eukaryotes, Viruses

• Bacteria, Fungi, Protists

What is the difference between autotrophs and heterotrophs?

• Autotrophs produce their own food (e.g., plants), while heterotrophs consume other organisms for energy.

• Autotrophs are organisms that consume other organisms for energy, while heterotrophs produce their own food.

• Autotrophs and heterotrophs are both types of plants.

• Heterotrophs can produce their own food, while autotrophs cannot.

Organisms are classified based on ________.

• genetic mutations

• similar characteristics and evolutionary relationships

• habitat and climate

• size and shape

What is the difference between a kingdom and a phylum in taxonomy?

• A kingdom is a lower taxonomic rank that includes multiple phyla.

• A kingdom is a higher taxonomic rank that includes multiple phyla, while a phylum is a rank that groups organisms based on major body plans and structural features.

• A phylum is a higher taxonomic rank that includes multiple kingdoms.

• A phylum is a rank that groups organisms based on their evolutionary history.

What is the significance of binomial nomenclature?

• It provides a standardized two-part naming system for organisms, consisting of the genus and species names.

• It is a method for classifying organisms based on their habitat.

• It helps in determining the age of an organism.

• It is used to identify the nutritional value of organisms.
