At the top of the classification system is the kingdom, the largest grouping. Animals make up one of five kingdoms in the natural world. The others are plants, fungi, bacteria, and protists (algae and other single-celled living things).

What are the two biggest groups of living things?
The two groups are: animals with a backbone these are called vertebrates animals without a backbone – these are called invertebrates. Vertebrates all have backbones.
Which major level of classification contains the largest grouping of species?
Kingdom: this is the largest, most general group. All organisms in a kingdom are then sorted into several phyla (phylum is singular). Example: Kingdom – Animalia: all animals.
What are the two smallest groups used to classify living things?
* Scientists name living things with the labels of the two smallest classification groups- genus and species.
What are the 3 main domains of life?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus.
What is the smallest group?
1 Answer. Domain is the largest group in that it breaks all living things into three broad categories. Species is the smallest group in the classification system.
Why do scientists classify living 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.
What protein do all animals have in common?
The exctracellular protein collagen (making the most abundant extracellular protein in animals) which is required in multicellular organisms to keep the cells together, which is exclusive to animals. Most enzymes responsible for metabolic pathways.
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.
What are the 5 living things?
Living things are divided into five kingdoms: animal, plant, fungi, protist and monera. Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
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.
What are the 8 levels of classification?
The major levels of classification are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
What is the most general level of classification?
The most general category in taxonomic classification is domain, which is the point of origin for all species; all species belong to one of these domains: Bacteria, Archaea, and Eukarya.
What are the 8 levels of taxonomy?
The current taxonomic system now has eight levels in its hierarchy, from lowest to highest, they are: species, genus, family, order, class, phylum, kingdom, domain.
