The kingdom is Protista, which includes simple eukaryotic organisms.
The most diverse kingdom is likely Animalia.
Using the US (six kingdom) model, the order would be Bacteria Archaea Protista Fungi Plantae Animalia *(protists are arguably a diverse and polyphyletic group, which will likely be phased out in any new hierarchy of living things)
in the kingdoms
There are more classes of organisms, since it is the most specific of the three.
Water is the most abundant compound in living organisms.

Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
Structures and Features
Diverse organisms in a large region.
No. Most hydrocarbons are not found in living organisms.
I think that all kingdoms DO have multicellular organisms, but most of the bacteria are unicellular. i hope this helps
Carbohydrates are the most important organic compounds in living organisms. Almost all organisms use carbohydrates as a source of energy.
Of all the terrestrial vertebrates, birds are the most diverse and successful. There are about 10,000 known living, or extant, bird species.
It is a bird and all birds are considered animals. Living things fit into several kingdoms. The most familiar to people are the plant and animal kingdoms. The other kingdoms are Monera, Protista, and Fungi. Viruses are not considered a "living" thing.
They are all living is the most common.
what is the function of oxygen in most living organism
Yes but most were single cell organisms
Most living organisms need oxygen, but a few anaerobic organisms don't need it .
