No one really knows how many species exist. Estimates of the total number of species vary from 3 - 30 million to 10 – 100 million, depending on the source. Taxonomists estimate that only 1.5 to 1.8 million species have been identified, but there are no central archives.

To help you remember the seven classification groups in order, remember this sentence:
Notice how 1 Kingdom will have many phyla. order, remember this sentence:
A phylum will have many classes…
One Kingdom will have 1000’s of species in it.
From the chart below, fill in the missing classifications. order, remember this sentence:
Plantae order, remember this sentence:
