You don't show the table...but you should see that the more complex an organism, the more chromosomes and the more genes it has.
A bacteria has a small genome. perhaps it has about 5000 genes. it also has 1 chromosome.
Yeast are more complicated than bacteria. Saccharomyces cerevisiae (the yeast that makes beer, wine and bread, has about 6300 genes and 16 chromosomes.
A human has 46 chromosomes (23 pairs), and has likely around 20,000 genes.
