The correct sequence of levels of hierarchy of classification of organisms from higher to lower is given in option 1: Phylum - Class - Order - Family - Genus.

To understand this sequence, it is important to understand the levels of hierarchy in the classification system. The classification of organisms is based on their evolutionary relationships and shared characteristics.

The highest level of hierarchy is the kingdom, which is not mentioned in the options. The next level is the phylum, followed by class, order, family, and genus. The species is the lowest and most specific level of classification, but it is not mentioned in the options.

In option 1, the correct sequence starts with phylum, then moves to class, order, and family, and finally ends with genus. This sequence follows the general pattern of hierarchy in the Linnaean classification system.

Option 2 is incorrect as it changes the order of family and order in the hierarchy. Option 3 is incorrect as it starts with family instead of phylum. Option 4 is incorrect as it starts with class instead of phylum.

Therefore, the correct answer is option 1.
