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.
For both plants and animals it is the species. But there are subspecies in animals and cultivars in plants.
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.
species
The highest level of classification, domain, has the least variety of organisms, encompassing only three major groups: Bacteria, Archaea, and Eukarya.
domain
The classification level with the fewest members is the domain level, which is the highest level in the biological classification system. It includes three domains: Bacteria, Archaea, and Eukarya.
For both plants and animals it is the species. But there are subspecies in animals and cultivars in plants.
The kingdom level of classification contains the most diversity and number of organisms. It is the broadest level where organisms are grouped based on shared characteristics.
Species
Species
The larger herbivores which are hunted by predators.

Yes, the Domain is the broadest classification level.
As you go down the levels of classification (from kingdom to species), the level of classification becomes more specific and increases. This means that organisms within the same species are more closely related to each other than organisms within the same kingdom.
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.
The lowermost category in the hierarchy of classification of a group of organisms is species. It is the most specific level in the classification system and represents a group of organisms that can interbreed and produce fertile offspring.
