L. Taylor Taxonomy

Which of the following lists the levels of taxonomy, from most specific to most general?

• Kingdom, domain, phylum, order, class, family, genus, species

• Species, genus, family, order, class, phylum, kingdom, domain

• Domain, kingdom, phylum, class, order, family, genus, species

• Domain, kingdom, family, class, order, phylum, genus, species

Organisms in the Kingdom Animalia are

• multicellular and heterotrophic

• multicellular and autotrophic

• unicellular and autotrophic

• unicellular and heterotrophic

Which of the following do plants and animals have in common?

• both are heterotrophic

• both are motile

• both are unicellular

• both are eukaryotic

If two organisms are in the same phylum, they must also be in the same

• class

• species

• family

• kingdom

The organisms Panthera leo and Panthera tigris are in the same

• cat

• genus

• organism

• species

Which statement is correct about the hierarchy of the taxonomic system currently used to classify organisms?

• All organisms of a given order belong to the same species.

• Many different classes of organisms belong to the same order.

• All organisms of a given phylum belong to the same kingdom.

• Many different families of organisms belong to the same genus.

Organisms are classified using a taxonomic system organized by the scientist Carl Linnaeus in the 1700s. The table shows the classification of the gray wolf and gray fox.

Taxonomic classification is important to biologists because it allows them to-

• discover new organisms.

• prove that foxes evolved from wolves.

• provide all organisms with both a common and a Latin name.

• identify organisms and study evolutionary relationships between them.

Adult mountain lions (Puma concolor) are almost 2 meters long. They have a black spot over each eye. The common names used throughout the United States for this species are listed.

Why is it best for scientists to use the name from the standardized taxonomic system?

• The standardized name differentiates mountain lions and pumas.

• The standardized name is less descriptive of the animal that has been observed.

• Communication with other scientists about mountain lions will be reduced.

• All scientists will be using one name for mountain lions.

The classification of four plants is shown in the table. Which two trees are the most closely related?

• onion and tulip

• tulip and common sweet flag

• onion and foxtail agave

• common sweet flag and tulip
