phylum
species
The classification group which has the least variety of organisms would be species. This is because it is the smallest class, and has been narrowed down beginning from kingdom.
domain
Kingdom: The highest level of biological classification.
Species. Explanation : Let us consider the next level of classification which is Genus. Genus is a group of closely related species. So, there are more number of organisms here as there are more than one specie. The next level is Family which is a group of closely related genera (Plural of genus). Now, here, there many genera which in turn contains many species. The levels of classification are such that each level contains more number of organisms than the previous level. So, it is called a Hierarchy of classification.

The species level contains the least number of organisms because it is the most specific classification level and refers to individual organisms that are most closely related and can interbreed to produce fertile offspring.
The classification of species.
It is referred as a Taxon.Taxon- groups or level of organization in which organisms are classified.
The addition of the domain level affected the classification of individual organisms with bacteria being split into two domains. There are actually trillions of bacteria on the planet.
Biodiversity. It refers to the variety of living organisms at all levels of organization, including genetic, species, and ecosystem diversity. Biodiversity is essential for the health and stability of ecosystems and provides numerous benefits to humans.
