Scientists classify animals to provide a standardized system of identifying and describing organisms that exhibit similar characteristics. Despite the vast diversity of animal species on Earth, categorizing these organisms into related groups simplifies taxonomic investigations.
Plants and animals are classified based upon their prevailing characteristics and traits. Biological organisms with similar characteristics are placed in the same group. The order of classification goes from the kingdom of the biological life form down to the genus and species of the organism. The f
All organisms belong to one of five kingdoms: animal, plant, moneran, fungi and protist. All living organisms fall into specific categories using taxonomy, which groups all living things into groups based on biological characteristics and traits. Taxonomy itself classifies as a distinct branch of sc
Biologists classify organisms based on physical characteristics and genetic relationships. Each specific kind of living thing is given a designated species name. Groups of related species are grouped together into a genus. Related genera are grouped into families, and families that show close relati
Matter comprises all substances that take up space and have mass, and it may exist as a solid, liquid, gas or plasma. Light and energy are not matter because they have no mass and do not occupy space.
Different species of bacteria are classified into five categories according to their shapes: cocci, bacilli, vibrios, spirochaetes or spirilla. Cocci are spherical, while bacilli are rod-shaped. Vibrios are shaped like commas, spirochaetes like corkscrews and spirilla like spirals.
Elements are classified as metals, nonmetals or metalloids. Noble gases are classified separately, although they are sometimes grouped with non-metals despite having different properties.
Rabbits, in scientific classification, belong to the Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Lagomorpha and Family Leporidae. Rabbits share the common name of Old World rabbit, domestic rabbit, or simply rabbit. These creatures belong to different genera depending on their species c
Scientists use a star's temperature to classify it into one of seven main groups referred to by the letters O, B, A, F, G, K and M, in descending order. Within those groups, stars receive a number classification based upon their temperature as compared to other stars within the same group. An additi
Minerals are most commonly classified by the Dana system. Minerals are identified according to hardness, specific gravity, color, luster, streak, cleavage and crystal form.
