Here's why:

* Hierarchical System: The classification system of life is hierarchical, meaning it groups organisms into increasingly inclusive categories.

* Order vs. Genus: An order contains multiple families, and each family contains multiple genera. Therefore, an order encompasses a wider range of organisms compared to a single genus.

* Specificity: A genus is a more specific grouping than an order. It typically includes closely related species that share common characteristics.

Example:

* Order: Carnivora (includes cats, dogs, bears, etc.)

* Family: Felidae (includes all cat species)

* Genus: *Panthera* (includes lions, tigers, leopards, jaguars)

Since a single order can encompass many families and genera, there are more organisms classified under a genus than under an order.
