What are the categories that scientists use to classify organisms in order from largest to smallest?

How do you classify living things?
Living things are classified into groups that start out large and become more specific in a system of classification called taxonomy. Scientists classify living things at eight different levels: domain, kingdom, phylum, class, order, family, genus, and species.
Why do scientists classify things?
Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA.
How do you classify living and nonliving things?
The term living thing refers to things that are now or once were alive. A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt.
