Concept:All individuals of a single kind of organism belong to the species, the most basic taxonomic unit.
Explanation:Taxonomic categories range from broad (kingdom) to specific (species).
A species includes all individuals that can interbreed and produce fertile offspring.
For example, all humans belong to the species
Homo sapiens.
Similarly, all rose plants of the same kind (e.g.,
Rosa indica) are grouped into one species.
The genus
Rosa contains many different rose species, not just a single organism type.
Therefore, the category for "all the individuals of a particular organism" is species.
Answer:Species.
