Classification and Taxonomy

What role do phylogenetic trees play in taxonomy?

• They classify species based on their physical characteristics.

• They illustrate the evolutionary relationships among different species.

• They provide a method for naming species in a hierarchical system.

• They show the geographical distribution of species.

What is the difference between a genus and a species?

• A genus is a specific group of organisms that can interbreed.

• A genus is a group of related species, while a species is a specific group of organisms that can interbreed.

• A genus is a classification of organisms that cannot interbreed.

• A genus is a broader category that includes only one species.

What happens to the variety of organisms as you move down the classification pyramid?

• The variety of organisms increases.

• The variety of organisms remains the same.

• The variety of organisms decreases.

• The variety of organisms becomes more complex.

What is binomial nomenclature?

• A system for naming organisms using three names: genus, species, and subspecies.

• A two-part naming system for organisms, consisting of the genus name followed by the species name.

• A method of classifying organisms based on their habitat and behavior.

• A naming convention that uses only the species name to identify organisms.

What are the two levels of classification used in scientific names?

• Genus and species.

• Kingdom and phylum.

• Order and family.

• Class and domain.

Define taxonomy.

• Taxonomy is a classification system based on shared characteristics.

• Taxonomy is a method of measuring biodiversity.

What is a species?

• A group of organisms that look alike and can reproduce among themselves.

• A classification of organisms based on their habitat.

• A type of organism that is extinct and no longer exists.

• A group of organisms that can only survive in extreme conditions.

What is the highest level of classification in the biological hierarchy?

• Kingdom

• Phylum
