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.enus is a group of closely related species.

Every organism can be classified at 7 different levels-kingdom, phylum, class, order, family, genus and species. Each level contains organisms with similar characteristics. The kingdom is the largest group and very broad.Each successive group contains fewer organisms, but the organisms are more similar.rganisms within a species are able to mate and produce fertile offspring. The following chart traces the classification of a grizzly bear through each of the 7 levels of classification. At each level, be aware of the characteristics the different organisms share.
