Biosphere contains the fewest number of species compared to community and population.
An order typically contains fewer organisms than a family. Orders are higher in the taxonomic hierarchy and are composed of several families, each containing multiple species. Families, on the other hand, are more specific and include a smaller number of closely related species.
Organisms in the domain Archaea are considered to share the fewest characteristics with other organisms. They have unique cellular structures and biochemical properties that distinguish them from bacteria and eukaryotes.
The principle of parsimony in phylogenetics is used to choose the simplest explanation for evolutionary relationships among species. By selecting the tree with the fewest evolutionary changes, researchers can determine the most likely relationships among species.
The largest genome typically belongs to amoebas, like Amoeba dubia, which can have billions of base pairs. Organisms with large genomes tend to have fewer genes per million base pairs due to the presence of repetitive and non-coding DNA sequences that lower the gene density.
The y chromosome, which only contains a few hundred genes.
The organizational unit that includes the fewest species of organisms is the species itself. A species is defined as a group of organisms that can interbreed and produce fertile offspring, and it typically encompasses a single type of organism. In contrast, higher taxonomic ranks like genus, family, or order include multiple species, making the species level the most specific and narrow classification in biological taxonomy.
For both plants and animals it is the species. But there are subspecies in animals and cultivars in plants.
The order of the Monotremata contains the fewest species, with only five extant species. These species include the platypus and four species of echidnas.

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.
Species within the class Cephalaspidomorphi, which includes the lampreys, comprise the smallest number of species among vertebrates, with around 38 recognized species.

Based on current data, Monaco is considered to have the fewest species of mammals in the world with only a handful of species present.
