How do organisms classified today?

Answer 1

One major way organisms are classified is by kingdom. There are five kingdoms, which group similar organisms by certain shared characteristics. These kingdoms are: Protista (single-celled eukaryotes), Monera (prokaryotes), Fungi (fungus and other decomposers), Plantae (for plants), and Animalia (animals).

Inside these kingdoms, you get into more specific classification groups, starting with phylum, then class, order, family, genus, and finally species. Examples of species include blue whales, aspen trees, and homo sapiens (the human species). Sometimes it's hard to remember the order of classification, so many people like to use acronyms. This involves taking the first letter of each group (K, P, C, O, F, G, S) and making a new, easier to remember phrase. A funny acronym for the classification system that I learned in my Biology class was Kids Playing Catch On Freeways Get Squished.

Answer 2

Scientists classify organisms using taxonomy, which defines groups based on shared characteristics.

For example, to be classified into the Animal Kingdom, an organism must have multiple cells, be eukaryotic, be motile (able to move) and must be heterotrophic (eat other organisms or their products).

Biological classification uses "ranks" which are (in order from most inclusive to least inclusive); Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species.

Answer 3

Organisms are classified based on their shared characteristics, such as genetic similarities, physical attributes, and reproductive traits. This classification system is called taxonomy and includes different hierarchical levels such as kingdom, phylum, class, order, family, genus, and species. Modern classification also considers evolutionary relationships to group organisms into clades that reflect their common ancestry.
