The term biological species means a group of organisms that can reproduce with one another in a biological environment and produce fertile offspring. The term species is defined as the most basic category in the system of taxonomy.
Taxonomy is the process of classification of biological living organisms according to their evolutionary relationship.
The Kingdom belongs to the higher level of taxonomy. This is the way to classify organisms in a broad spectrum rather than like species. It consists of organisms which are similar in morphological or genotypic format only.
