See also the following terms from the Biology Dictionary. Biology Dictionary entries include examples and a short quiz for each term.
Domain (Biology Dictionary, n.d.)
"In biology, a domain refers to the largest of all groups in the classification of life. There are currently 3 agreed groups at this level, the Archaea domain, Bacteria domain, and Eukarya domain. Each domain contains a collection of organisms with similar properties and evolutionary histories, as scientists have organized them. It should be noted that while the three domain system is widely accepted and taught, it has been contested by a number of scientists." ("Domain", n.d.)
Phylum (Biology Dictionary, n.d.)
"Phylum is a taxonomic ranking that comes third in the hierarchy of classification, after domain and kingdom. Organisms in a phylum share a set a characteristics that distinguishes them from organisms in another phylum." ("Phylum", n.d.)
Kingdom (Biology Dictionary, n.d.)
"In the study of taxonomy, the rank of kingdom is just below domain... All of life, thought to come from a single origin, can be broken down into lower levels of classification, such as a kingdom or phylum." ("Kingdom", n.d.)
Class (Biology Dictionary, n.d.)
"Class was the most general rank proposed by Linnaeus; phyla were not introduced until the 19th Century. There are 108 different classes in the kingdom Animalia, including Mammalia (mammals), Aves (birds), and Reptilia (reptiles), among many others." (“Class”, n.d.)
Order [and family] (Biology Dictionary, n.d.)
"Order is more specific than class. Some of Linnaeus’ orders are still used today, such as Lepidoptera (the order of butterflies and moths). There are between 19-26 orders of Mammalia, depending on how organisms are classified—sources differ." (“Order”, n.d.)
Genus (Biology Dictionary, n.d.)
"A genus is a group of species that are closely related through common decent. A genus represent one of several hierarchical categories called taxa (singular taxongenera (plural of genus) include only a small group of species which evolved from a relatively recent common ancestor." (“Genus”, n.d.)
Species (Biology Dictionary, n.d.)
"A species is a group of organisms that share a genetic heritage, are able to interbreed, and to create offspring that are also fertile. Different species are separated from each other by reproductive barriers. These barriers can be geographical, such as a mountain range separating two populations, or genetic barriers that do not allow for reproduction between the two populations. Scientists have changed their definition of a species several times throughout history." (“Species”, n.d.)
Classification and Ecosystems | Overview: Articles
Biological classification (Britannica Middle, n.d.)
"In biology, classification is the process of arranging organisms, both living and extinct, into groups based on similar characteristics. The science of naming and classifying organisms is called taxonomy. The term is derived from the Greek taxis (“arrangement”) and nomos (“law”)." ("Biological classification", n.d.)
Binomial Nomenclature (Biology Dictionary, n.d.)
"Binomial nomenclature is the system of scientifically naming organisms developed by Carl Linnaeus. Linnaeus published a large work, Systema Naturae (The System of Nature), in which Linnaeus attempted to identify every known plant and animal.... Binomial nomenclature was established as a way to bring clarity to discussions of organisms, evolution, and ecology in general." (“Binomial Nomenclature”, n.d.)

A Closer Look at Living Things: Introduction to Biology by
Publication Date: 2011
Life comes in all shapes and forms, and living entities dwell in all types of habitats. There are seven characteristics that all life forms shareOCothe ability to move, to sense, to respire, to consume nutrition, to grow, to reproduce, and to excrete waste matter. Complete with annotated illustrations that clarify complex structures and life processes, this volume surveys the parts, characteristics, and classifications of various living things and explores the evolution of life in general.
The World of Animals by
Publication Date: 2007
Animals come in all shapes and sizes! The lively images, compelling facts, and captivating sidebars work in conjunction with the supportive text and a glossary and index to give readers plenty of information on taxonomy. Readers will discover the various kingdoms and classes of the animal world including echinoderms, arthropods, chordates, amphibians, birds, and mammals. To aid in engaging readers in further scientific topics and themes, an alluring hands-on lab activity is included!
Zoology: Cool Women Who Work With Animals by
Publication Date: 2017
Love to work with animals? Want to study them in the wild? Wish you could become a zookeeper? Become a zoologist! Zoology is the study of everything having to do with animals, including how and why they look, act, and behave in their environments and with other animals. As a zoologist, you might go on an expedition to Africa to study how elephants solve problems. You could take care of tigers at a zoo. You might even study how climate change can affect underwater creatures. In Zoology: Cool Women Who Work With Animals, readers ages 9 to 12 are inspired by stories of women who have made great strides in a field that requires commitment, courage, and creativity to pursue. Many of you have heard of the famous zoologists Charles Darwin, Jack Hanna, and Steve Irwin, but do you know Terri Irwin, Dian Fossey, and Rachel Carson? For many decades, female zoologists have been defining the field by advancing the global environmental movement while researching and advocating for all species of animals. Zoology: Cool Women Who Work With Animals introduces readers to three women in the field of zoology who are making an impact and inspiring the next generation of zoologists. Stephanie Kim is a graduate student in Canada studying different species of birds. Elise Newman works as a zookeeper at the San Diego Zoo Safari Park. Dr. Erin Seney is a sea turtle researcher with the University of Central Florida. Nomad Press books in the Girls in Science series supply a bridge between girls' interests and their potential futures by investigating science careers and introducing women who have succeeded in science. Compelling stories of real-life zoologists provide readers with role models that they can look toward as examples of success. Zoology: Cool Women Who Work With Animals uses primary sources, essential questions, and knowledge connections to encourage both boys and girls to explore the animal world while being inspired to ask what role they might play in the field of zoology.
Classification and Ecosystems | Overview: Videos
"In terms of biological classification, organisms are classified, or grouped, with other organisms that they are most closely related to. These small groups are then classified together into larger groups and so on, until we reach the top level of classification which places organisms in one of three biological domains - Archaea, Bacteria and Eukarya. When each organism is classified in this way it allows scientists to see the relationships between different species, and make sense of the hugely diverse array of life." (FuseSchool, 2016)
