What is the second largest group of living things?
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 is the largest group of organisms?
The largest group of organisms is called a domain. The organization of living things ranges from domain, to kingdom, phylum, class, order, family, genus, and species.
What is the largest group of classification?
|genus||the largest group within a family|
|species||refers one type of organism whose members can breed sucessfully|
|domain||three new groups, the largest taxon|
|protist||mostly single-celled eukaryotic organisms that have a nucleus|

What are the 8 classifications of living things?
There are seven major levels of classification: Kingdom, Phylum, Class, Order, Family, Genus, and Species. The two main kingdoms we think about are plants and animals.
What are the three types of living things?
Living things are divided into three groups based on their genetic similarity. The three groups are: Archaea: very ancient prokaryotic microbes. Two types of living things can be generalized to prokaryotes (which are bacteria and archae) and eukaryotes (which are animals, plants, protists, and fungi).
What are the 3 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 single-celled organisms whose cells have no nucleus.
What are the two largest groups of animals?
Mollusks are the second-largest group of invertebrates, with 50,000 living species. Arthropods are the largest and most diverse of all animal groups. They have segmented bodies supported by a hard external skeleton (or exoskeleton).
What is the largest group in the animal kingdom?
Phylum Arthropoda is the largest of all the phyla of animals according to the number of species in this particular group. Arthropods are characterized as animals with jointed legs and a hard external skeleton made of chitin. Animals in this group include spiders, insects and crustaceans.
Which group of organisms has the most discovered species?
In terms of numbers of species, insects certainly represent the largest percentage of the world’s organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
What is the smallest group of classification?

What are the 8 levels of classification from largest to smallest?
1. Linnaeus’ hierarchical system of classification includes seven levels called taxa. They are, from largest to smallest, Kingdom, Phylum, Class, Order, Family, Genus, Species.
What are the 6 kingdoms of life?
Organisms are classified into three Domains and into one of six Kingdoms of life. These Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. Organisms are placed into these categories based on similarities or common characteristics.
What are the 7 kingdoms of life?
7 Kingdoms of Life
- Kingdom: Animal.
- Kingdom: Eubacteria.
- Kingdom: Fungi.
- Kingdom: Protista.
- Some examples of protists are: amoeba, paramecium, euglena, algae, and giant kelp.
- ~The Kingdom Eubacteria is home to many prokaryotic bacteria. ~They are producers, consumers and decomposers.

Most living things need food, water, light, temperatures within certain limits, and air. Living things have a variety of characteristics that are displayed to different degrees: they respire, move, respond to stimuli, reproduce and grow, and are dependent on their environment.
How many types of living things are there on Earth?
Humans share the planet with as many as 8.7 million different forms of life, according to what is being billed as the most accurate estimate yet of life on Earth.
What are the 3 types of domain?
Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), the cell’s membrane lipid structure, and its sensitivity to antibiotics. 3. The three domains are the Archaea, the Bacteria, and the Eukarya.
What are the 5 kingdoms and 3 domains?
Under this system, organisms are classified into three domains and six kingdoms. The domains are Archaea, Bacteria, and Eukarya. The kingdoms are Archaebacteria (ancient bacteria), Eubacteria (true bacteria), Protista, Fungi, Plantae, and Animalia.
What are the three types of domain?
There are three main domains of learning and all teachers should know about them and use them to construct lessons. These domains are cognitive (thinking), affective (emotion/feeling), and psychomotor (physical/kinesthetic).

Are there more humans or animals in the world?
Recent figures indicate that there are more than 1.4 billion insects for each human on the planet An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. Ants have colonised almost every landmass on Earth.
How many species go extinct every day?
These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true – i.e. that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year.
