In taxonomic, the organism is classified based on some similarities. In upper division, the similarities should be more general and in the lower division, the similarities will be more specific. It was mostly based on an organ, example: vertebrate.
An organism with the same phylum could be put in different order.
But the organism with the same order should have the same phylum and class too since order is located below the phylum. That means the organism with the same order should have more similarities than the organism with the same phylum. Those similarities are tightly correlated with the evolutionary relationship.
The image is not really helping since it was showing kingdom division, not the sequence of the taxonomic division.
The answer is 40 m, because you must cross multiply by using proportions.
I showed my work below.
<span>Aquatic organisms and the physical and chemical components of their environment are inseparably inter-related and interact with other. Flow and water chemistry are the primary factors governing life in riverine habitats, and both are closely related to seasonal variations.</span>
