Classifying organisms helps scientists organize and answer questions about them. Organisms are organized by shared classifications. Scientists use physical and chemical characteristics to classify and organize organisms.
One method of classification is Linnean System.
The Linnean system is used in the science of taxonomy, it uses seven main groups:
There is another more general group in the Linnean System, Domains.
Domains are the biggest group, and there are three:
Bacteria is made up of mainly single-celled organisms, they reproduce by cell division, don't have a nucleus, and most can make their own food.
Archaea is made up of single celled microorganisms that can make their own food.
