Answer: There are fewer organisms in the levels of classification.
Step-by-step explanation:
As we move down towards the species level then the number of organism becomes less. More number of organisms are found at the top of the classification but as we move from domain towards species their number decreases.
This is because the similarity of organism at domain level is more and the similarity at species level is less specific.
Hence, the number of organism becomes lesser in number as we move down towards the species level.
